TITLE: I. Photoelectromotive Forcestin Anthracene
PERIODICAL* Fizika tverdogo tela, 1960, Vol. 2, No. 10, pp. 2517-2525
TEXT: The authors give the results of an investigation of the photo-
electromotive forces which are generated in an anthracene sample
irradiated with intermittent light ( X - 3650 A). This wavelength
corresponds to the main absorption region of anthracene. The sample was
also irradiated with non-monochromatic light (2L >3100 A). A mercury
quartz lamp served as a light source, and suitable filters gave the
wavelengths necessary for the experiments. The interruption of the light
ray was produced by means of a rotating disk, which was driven by an
electromotor. The monocrystalline samples were bred according to a method
suggested by LipBett (Ref. 15), and the polycrystalline ones by
sublimation in vacuo. The samples investigated had different kinds of
pulses of the photo-emf, as regards their shape and polarity. Freshly

produced monocrystalline samples had at first positive pulses. After
several seconds, these positive pulses vanished, and negative pulses of
the photo-emf appeared. The oscillogram in Fig. 3 has a negative pulse
at a temperature of 180C. On polycrystalline sampl'es also, the authors
were able to prove the existence of positive pulses; however, the latter
did not change. The phenomena on the single crystalline samples are
explained as due to photochemical processes on the anthracene surface.
Figs. 5 to 7 show the dependence of the above described effects on the
irradiation intensity and the temperature. Summarizing, it is stated that
in the irradiation of anthracene with ultraviolet light (X - 3650 A), the
light is adsorbed in a layer of thickness lo-4cm. In this layer, excitons
are generated, which are looked upon as moving excitation processes in
molecular crystals. In the case of a weak exciton-phonon coupling, the
exci.ton decay may occur either on the defects or on the surface of the
sample. In this case, either a nonradiative mechanism is possible, or a
de-excitation of a luminescence quantum, or also the production of an
electron-hole pair. In the case of increases of temperature, these
pro3esses may occur not only on the defects, but also as the result of

exciton-phonon interaction. As the diffusion length of the excitons in
anthracene is not greater than 0.15 micron. it may be assumed that the
production of electron-hole pairs takes place in the same surface layer
in which the light is absorbed. The holes, which have greater mobility,
generate the positive pulses. On the action of light having a wavelength
less than 4000 A, a photochemical change occurs in the presence of the
air-oxygen on non-purified surfaces. In this way, products of a photo-
oxidation of anthracene occur near the layer in which the carriers are
produced, which have an affinity to holes. The settling of holes on the
adhesion levels leads to a decrease of the positive pulses. The
anthracene used came from the Kharlkovskiy zavod khimicheskikh reaktivov
(Kharlkov Factory of Chemical Reaaents). Ye. K. Putseyko (Ref. 12);

TRANSLATION: With a duration of illumination t=l msec on pure polycrystalline and
single crystal samples of anthracene there are observed positive pulses of the photo-
current with a constant of drop r;z--2.8 msec and on samples, subjected to photo-
chemical changes, negative pulses with -r= 1 mscc. For positive pulses -r does not
change noticeably with temperature, while for negative pulses, f decreases with
a rise in temperature. Polarity of the pulses depends only on the purity of the
qppple. The nature of the observed electromotive force is nondirectional.- How-

ever, at t > 10 msec the electromotive force had identical polarity both in pure
and in phot7ochemically modified samples. The build-up process is exponential;
r;z;O.l second. It is shown that in this case the processes encompass the whole
crystal, whereas at small t they are of a more front-wall character. At large t,
apparently there occur photo electrochemical processes. At small t, however, the
appearance of photo-electrmotive force is connected with diffusion of the light
current carriers.

TITLE: The temperature dependence of the dark currents in
anthracene
PERIODICALs Fizika tverdogo tela; V. 4, no. 11, 1962, 3104 - 3-109
TEXTt The values for the thermal activation energy E of volume and surface
currents in anthracene crystals vary between 1.4 and 2.7 ev as given by
various authors (e.g.,Proc. Phys. Soc. 74, 756, 1959; Bull. Chem. Soc.
Japan, 29, 131, 1956; Proc. Roy. Soc. A234, 1~4, 1956). Measurements have
recently been made in order to obtain more accurate values. The samples
used were polycrystalline and monocrystaliine, prepared by various methods,
The base substance was synthetic anthracene purified by zone melting.
Single crystals were grown in the melt and also in the solution, poly-
crystals obtained by sublimation in vacuo on a PbO coated quartz glass
base. Samples kept in air for a short time showed no influence of the
oxygen. The measurements were made in purified nitrogen. The dectrodes
were brass, Al or Pt attached to surfaces of the samples with Aquadag.

The temperature dependence B102/B104
Within a temperature range of' 75-115 0C the temperature dependence of the
'dark current is stationary and can be expressed by I - 1 0exp(-E/2kT). The
slope of the curves was found to be In I - f(l/T), indicating that E does
not depend either on the method by which the sample was obtained or on the
type of crystal used. F also was independent of the crystallographic
direction,.equal to 1.98 10-04 ev. for the surface current and for the
volume current. When the measurements were made in oxygen or air the
values of E ranged from'1.46 to 1.60 ev. Since E is considerably smaller
than the singlet level 1E 1 (3.10 ev) the first stage of the carrier pro-
duction in anthracene cannot be attributed to the excitation of this
singlet level. E is also found above the triplet level 3E,(1.64 ev),
E - 3E might also give the thermal activation energy of the carrier mobili-
1
ty: in fact it is equivalent to the photoctirrent thermal activation
energy, 0.34 ev. (Canad. J. Chem. 35, 998, 1957). There are 3 figures
and 2 tables.

ABSTRACT:
Card 1/3
The author describes the use of piezoceramic capaci-
tors as transducer elements in electrometer circuits.
The dynamic capacitance of a capacitor made of VK-2
ceramic may be easily changed by six to eight times,
which corresponds to a modulation factor of 0.7. Accor-
ding to T.N. Verbitskaya ZR-ef 9, the capacitance of
a piezoceramic capacitor will change in the longitudi-
nal and in the transverse field. Based on this obser-
vation, a special O.8X5x8 mm capacitor wa-s used, made
of a VK-2 ceramic plate with four terminals in two mu-
tually perpendicular directions with~,_-$**~!A capacitan-
ces of 20 and 1000 picofarads, respectively. The high-
er capacitance was used for the modulation. A hystere-
sis loop was obtained, as shown in the oscillogram in

tional ceramic capacitor. The transducer may be used
in a wide frequency rangeg while reed vibrators will
hardly exceed 100 cps. The transducer may be impro-
ved with a future progress in the technology of pro-
ducing piezoceramics and may be used for building elec-
trometers. The author expresses his gratitude to S.S.
Smirnov, who participated in this work. The publica-
tion of this article was recommended by the Depart-
ment of Physics of the Moskovskiy inzhenerno-fiziche-
skiy institut (Moscow Physics Engineering Institute).

cording to D.M. Kazarnovskiy's method fR-ef g. The pie-
zoceramic transducer was used in a circuit arran-ement,
shown in the circuit diagram in Fig 2. This circuit
arrangement includes an alternating current amplifier
and a rectifier. For compensation of linear inductions
and phase shift, a differentail stage and a phase shif-
ter are used. The transducer showed during tests at
1900 cps a sensitivity of 1.2-10-12 amps at a direct

ceed 3-10-11 amps. Frequency fluctuations had a strong
influence on the drift. The transducer described by
the author is inferior in its characteristics to the
best designs of mechanical dynamic capacitors, but it
has also a number of advantages. Above all, it is

TITLE: Catalytic Dehydrogenation of Isohexanec
PERIODICAL: Izvestiya Akademii nauk SSSR. Otdeleniye khimicheskikh nauk,
1960, No. 89 pp. 1457-1465
-TEXT: The present paper is a continuation of the investigation into the
dehydrogenation of hydrocarbons of different strubtuies over an aluminum-
chromium-potassium catalyst. The catalyst is discussed in detail.in Ref.l.
The 2-methyl pentane, 3-methyl pentane, and 293-dimethyl'butane used in
this investigation were prepared by the Grignard reaction. 2,2-dimethyl
butane was obtained by pyrolysis of pinacoline alcohol acetate ~Ref. 2).
The experiments were carried out in a continuous system, at 500 C and
Atmospheric pressure and a flow rate of 0--5 h-1. The catalyst was re-
generated after every experiment by oxidation in air at 700 0 C. The
properties of the isohexane catalyzates are listed in Table 1 and the

composition of the gases formed in Table 2. For comparison, the correspond-
ing data for n-hexane are also given. As is shown, dehydrogenation of
2-methyl pentane, 3-methyl pentane and 2,3-dimethyl butane yields 34-40%
unsaturated hydrocarbons. Isohexanes form up to 2% and n-herane up to
43% aromatic hydrocarbons. 2,2-dimethyl butane was found to form 15% un-
saturated hydrocarbons. Formation of aromatic hydrocarbons was not ob-
served. The gaseous.products formed from 2-methyl pentane, 3-methyl pen-
tane and 293-dimethyl butane contained 84 - 90% byd2ogen, 9 - 12% methane,
ethane, and propane, and 1 - 4% of other alkenes and alkanes. The gas ob-
tained from 2p2-dimethyl butane contained 72.6% hydrogen) 21.2% C -C
alkanes and 6.2% of other hydrocarbons..These data show that 2,2-limhhyl
butane is less stable under the given conditions than all other isohexanes.
This conclusion was confirmed by the examination of the-liquid catalyzates.
Analytical data on the catalyzatecomposition allow the conclusion that, in
hydrogenation under the given conditions, all the isohexanes form alkenes
containing essentially 6 aarbon atoms. Isomerization was not observed in
dehydrogenation of 3-methyl pentane. Slight isomerization occurred during
dehydrogenation of 2-methyl pentane and 2,3-dimethyl butane. 2,2-dimethyl
butane formed alkenes during the catalytic reaction. Approximately half
of these alkenes were 'Asomerizatlon products: 4-methyl 2-pentene,

TITLE: Dehydrogenation of n-Nonane on an Aluminum-Chromium Catalyst
PERIODICAL: Doklady Akademii nauk SSSR, 1959, Vol 129, Nr 1, pp 128-130
(USSR)
ABSTRACT. In connection with previous investigations (Refs It 2) the authors
wanted to dehydrogenate n-alkanes with higher molecular weight
on the catalyst mentioned in the title. Data from publications are
very scarce (Ref 3). The investigations were carried out at
various temperatures and volume rates. The method described
earlier (Ref 2) was appliedo The gas.formed due to reaction
contained 92-97% hydrogen, 1.5- 3.5% unsaturated and 1-0- 4-5%
saturated hydrocarbons. Table I and figure 1 show the results.
Table I shows that with a volume rate of 2.1 h-1 the olefin
content is increased from 8% to not more than 14-15% if the
temperature increases from 400 to 4750o At the same time the
content of aromatic hydrocarbons increases considerably, namely
from traces to 15-16%. Thvs a temperature of 4000 is optimum with

An increase in volume rate from 2.1
the olefin yield; at the same time the content of aromatic
hydrocarbons decreases from 15-16% to 10-12%. In order to
investigate the composition of unsaturated hydrocarbons the
product of catalysis was conducted over silica gel treated with.
HCJ and hydrogen peroxide (according to A.V. Topchiyev et al.
(Aef 4)). Thus the paraffin part.of thegas produced and a 95%
concentrate of unsaturated hydrocarbons were separated. The latter
was analyzed by means of the Raman spectra. It was found that
olefins consist of nonene-4 mainlyq although the presence of other
nonenes may also be possible. The paraffin part seems to consist of
pure n-nonene. Isoalkanes with a tertiary carbon atom are missing
(Ref 5). Thus the investigation proved the possibility of
selectively dehydrogenating n-nonane below a nonene yield of 8-9%
and without considerable aromatization reaction. There are
1 figure, 1 table, and 5 references, 4 of which are Soviet.

TITLE: Dehydrogenation of n-Hexane on an Aluminochromium Catalyst
(Degidrogenizatsiya n-geksana na alyumokhromovom katalizatore)
PERIODICAL: Doklady Akademii nauk SSSR, 1959, Vol 125, Nr 6, pp 1272-1274
(USSR)
ABSTRACT: A survey of publications on the reaction mentioned in the title
(Refs 1-2) shows that neither the instructions concerning the
reaction nor the yield of hexenes nor the formation of aromatic
hydrocarbons under the given conditions have been hitherto
discussed. Papers on the afore-mentioned reaction on oxide
catalysts lack. Further references follow (3-6). Table 1 shows
the data given in the publications concerning the reaction
mentioned in the title in the presence of chromium and with the
aromatization of n-heptane. This shows that catalyzates have
hitherto been obtained by various research workers which contained
considerably less unsaturated hydrocarbons than aromatic ones.
On the strength of their investigations carried out in the last
Card 1/3 years the authors drew the conclusion that it is possible to

Catalyst
change considerably the ratios of the yields of the two afore-
mentioned hydrocarbon'types, i.e. from 0.14 to 2.11 by changing
the production of the catalysts mentioned in the title,
furthermore, by the introduction of oxides of alkali metals,
finally by changing the instructions concerning the reaction.
The catalyst without alkaline additions was the best of all
catalysts investigated, as far as the maximum yields of unsatura-
ted hydrocarbons are concerned. It was produced by the
saturation of aluminum oxide with ammonium bichromate solution.
Unsaturated hydrocarbons with a yield of 2W., and not more than
lel. benzene were obtained from n-hexane at 5001 and a rate of
passage of 0-5 h- 1. It was the authors' object to suppress the
aromatization even more in this investigation. All factors
were investigated for this purpose: temperature, rate of passage,
and individual parts of the catalyzate were analyzed etc. Table
2 and figure I show the results. The gais produced by the trans-
formations of n-hexane at 475 and 5000 contained 90.6-95-3"~')
hydrogen, up to 1.8~b unsaturated hydrocarbons, and 2-7-7-5~a'

however, by 9-13~6. Thus, it was found that the dehydrocycliza-
tion of n-hexane practically does not take place under the
given conditions, whereas hexenes are produced in rather con-
siderable quantities. The result is of general importance
since the authors succeeded in suppressing the aromatization
of an n-alkane which is capable of immediate dehydrocyclization
in the presence of an aluminochromium catalyst. The dehydrogena-
tion of n-hexane is rather considerable. There are 1 figure,
2 tables, and 8 references, 6 of which are Soviet.

TITLE: Effect of Temperature and Volume Rate on the Dehydrogenation

PERIODICAL: Izvestiya Akademii nauk SSSR. Otdeleniye khimicheskikh nauk,
1959s Nr 6, Pp 1432-1437 (USSR)
ABSTRACT. As an introduction some methods already known in publications
and concerning the aromatization of alkanes are discussed.
Special mention is made of Moldavskiy1s, Kamueber's and
Kobyllskayals method (Ref 2). In the present paper the be-
havior of cyclohexane in the presence of typical dehydrogena-
tion catalysts of the composition A12 0 39 Cr203 9 K20
(90.7 : 5.6 : 3.7 mol%) is investigated. Experimental yields
were compared to the eqi~ilibr_ia which were determined by
thermodynamic calculations. The dehydrogenation of n-hexane
was accompanied by aromatization in which much more benzene
than olefines was formed. The method used has already been
described in reference 6. The refractive index, iodine number,
and aromatic hydrocarbon content (according to the method of
relative dispersion) were determined in the liquid catalysate.
The gas analysis was carried out in a N'TI-2 unit. Characteristic
Card 1/2 data found by the experiments are compiled in tables 1-4-

Effect of Temperature and Volume Rate on the Dehy-_;rooge:~Pation cf n-Eex-e
According to Ito Aromatization Conditions
It can be seen from the results that- the hexane yield is in-
dependont of temparature change and volume rate whereas -the
benzene yield increases rith a mounting temperature but de-
creases with an increasing volume rate. The thermodynamic
oalculations carriad out show that a maximu-n of 73~o of the
amount of cyclohexane corresponding to the state of equi-
librium can be obtained. The authors conclude by thanking

TITLE: The production of alkenes of a composition C6-ClO
by catalytic dehydrogenation of.alkanes
PERIODICAL: Neftekhimiya, v.2, no.4, 1962, 457-465
TEXT: The reaction of dehydrogenation of alkanes (C6-Cl6) was
investigated in order to find appropriate'catalysts and conditions
for selective production of the corresponding alkenes, as well as
to study the possibility of controlling reactions of
dehydrogenation, dehydrocylization and cracking. The present
paper is a generalization of the authors' researches on these
problems. It was shown on examples of 2-methylpentane,
3-methylpentane and 2,3-dimethylbutane that alkanes C6, the lbng V/
chain of which contains less than 6 carbon atoms, are comparatively
easily dehydrogenized on an alumochromopotassium catalyst at 5000C
and a volume velocity of 0.5 h-1, yielding from 86 to 89% of
catalysate containing from 32 to 40% of alkenes. Conditions
for dehydrogenation of 2,2-dimethylbutane were found under which

96.5% yield of catalysate, containing 10.4% of
3,3-dimethylbutene-I (practically equilibrium yield) and 4.6% of
cracking products were obtained (no details given). Some
catalysts and proceso conditions for selective dehydrogenation of
n-hydrocarbons C6-Clo were found under which about 10% yields of
corresponding alkenes were obtained. The possibility of selective
dehydrogenation of n.alkenes (C6-Clo) into alkenes was indicated
by comparison of results obtained with various catalysts which
point4d out the existence of two kinds of active centres on
alumochromium catalysts - dehydrogenating and dehydrocyclizing.
The activity of dehydrocyclizing centres can be considerably
lowered by a treatment of the catalyst with cyclopentadiene or
furfurole with subsequent regeneration. The possibility of
controlling dehydrogenation, dehydrocyclization and cracking
reactions by carrying out the process in a fluidized bed of an
appropriate catalyst was demonstrated, e.g. on dehydrogenation
of n.nonane over Al 0 + Cr20 3 catalyst at 5000C selective
hydrogenation; at 908*C do hydrogenation and dehydrocyclization;
with K-5 catalyst at 6000C - dehydrogenation and cracking with
A1203 + Cr203 + K 0 catalyst at 6000C dehydrogenation with

TITLE: Composition of the Products of Dehydration of C - C 9
n-Alkanes Over Aluminum-chromium-potassium Cata~yst
PERIODICAL: Izvestiya Akademii nauk SSSR. Otdeleniye khimicheskikh nauk,

TEXT: In the present paper the authozsstudied the structure of unsaturated
and aromatic hydrocarbons, but above all the composition of alkenes
formed from n-alkanes at 5000C over an aluminum-chromium-potassium catalyst
and a volume velocity of 0.5 h-1. n-hexane, n-heptane, n-octine and n-nonane
were used for this reaction. The unsaturated hydrocarbons formed were found
to consist mainly of alkenes. As regards number of carbon atoms, they cor-
respond to the initial alkanes and have double bonds in the positions 2, 3
or 4. The catalyzate of n-hexane was found to contain 1-hexene also, but
in much smaller amounts than 2- and 3-hexenes. The catalyzates of n-heptane,
n-ootane, and n-nonane possibly cofttain other alkenes in addition to the
2-heptene, 4-octene, and 4-nonene actually found. The quantities contained,
however, are so small that they were not detectable in the Raman spectra.

All catalyzates were found to coniain dienes, the structures of which could
not yet be established exactly. The structure of the aromatic hydrocarbons
formed from n-alkanes becomes more complicated as the molecular weight
of the initial alkane increases. n-hexane forms benzene, n-heptane toluene,
n-octane mainly xylenes and ethyl benzene as well as lower-boiling aromatic
hydrocarbons, benzene and toluene. The aromatic hydrocarbons formed from
n-nonane consist mainly of methyl ethyl benzene, trimethyl benzene, and n-
pzopyl- and isopropyl benzenes. Apart from these, the catalyzate contains
lower-boiling hydrocarbons, benzene, toluene, and ethyl benzene. There
are 5 tables and 5 references: 3 Soviet and 2 British.

the charge were caught by a device in which cooling by means
of liquid nitrogen was applied for the turpose of freezing out
sulphurous acid anhydride and sulphuric anhydride. According
-to Averbukh, B,D,, (Ref,7) the quantity of forming, sulphuric

ABSTRACT: In earlier work one of the authors of the paper found tha-"'
there is a direct relation and a temperature correspondence
between the changes -w--aking place in various metal compounds
and the changes in the properties of the individual
elements forming these compounds. In this paper, the
authors aimed at verifying this conclusion for ir'cn oxides
and thus to try and explain anomalous phenomena taking
place in reduction processes. To bring the theoretical
investigations nearer to industrially used materials, the
authors used in the experiments magnetite and not pure

reduction werelinvestigated on a circular vacuum test rig
(described in an earlier paper) (Ref 20) inside a hydrogen
atmosphere; the initial pressure was 408 mm, hydrogen
was sucked through a layer 25 mm high,weighing ? g, with
particle dimensions between 0.4 and 0.6 mm.. The tSmperature
in the layer was measured with an accuracy of + 1 C~ the
circulation speed was 600 ml./min with a volum7e of the
system of 800 ml. The gaseous reaction products were
frozen out in a trap which was cooled by liquid nitrogen.
The ore was heated to the desired temperature in vacuum
(10-2 to 10-3 mm HS). Following that, a quantity of
hydrogen was introduced which was equal in every case,
maintaining the pressure constant. The speed of reduction
was judged from the consumption of hydrogen in the closed
system which was measured every minute. Every three
minutes the system was joined to a vacuum and, after that,
the temperature was readjusted and the gaseous phase
renewed. It could, therefore, be assumed that a number
Card2/? of successive measurements, carried out at 3 min intervals,
provided the isotherm of the reduction of the ore. At

each temperature the experiments were carried out with a
fresh ore specimen. Since the aim of the work was to
elucidate the existence of a relation between the changes
in the properties of the iron, at temperatures at which it
is known that phase transformations take place, and the
kinetics of reduction of iron oxides under equal conditions,
theinvestigationsowere carried out in the temperature
range 700 to 910 0. In tbas temperature range magnetic
as well as polymorphous 8ran formations take place in the
iron at 768 and 906-910 C, respectively. The speeds of
reduction of magnetite, expressed in terms of hydrogen
consumption during the first 3 min as a function of the
temperature, are grqhed in Figure 1. It can be seen that
the graph contains several anomalous sections. The
obtained results justify revision of certain views expressed

on the kinetics of reduction of iron oxides. In the
first instance, it is quite evident that sintering
phenomena, changes in the porosity and recrystallisation
of the studied substances and in the reaction products7
changes of speed of diffusion and the speed of chemical
reactions do occur in the course of variation of the
temperature during reduction of the ores and of iron
oxides. The most plausible explanation of the anomalous
phenomena in the processes of reduction is based on the
changes of the state of the iron atoms as a function of
the temperature, particularly as regards phase transt)r-
mations. The obtained results (Figure 1) indicgte that
the jumps in the speed of reduction at ?52-?56 C
correspond to the magnetic transformation of the iron
and not to the Curie point of the magnetite. Thus, the
change in the character of the chemical process at the
Card 4/7

SOV/24-58-4-22/39

temperature of magnetic transformation of the iron
confirms the conclus"&.on that the anomalous phenomena in
the chemical and physical processes at various
temperatures are based on the changes in the state
of the atoms and not on changes of the crystal lattice.
It can be seen from the graph, Figure 2 (temperature
coefficient of the electric resista-nce of iron) that the
thermal coefficient of the electric resistance c4anges
appreciably in the temperature range 400 to 450 C and
also at 550 and 650 '~O-

The following conclusions are arrived at:
1) The apoed of reduction of magnetite with hydrogen
decreases in jumps and then again increases within n&rrow
temperature range approaching the followiag temperatures:
magnetic transformation of the iron (752 C), 0
Fert~ FeY transformation (906 wC) and at about 820 C~
at which the properties of the iron change considerably.
2) Using the example of the jump-like change in the
speed of reduction at temperatures of the magnetic
transformation of iron it is shown that the observed
anomalies in the kinetics of the process are based on the
changes of the electron structure of the iron atoms.
3) The anomalies in the kinetics of reduction of ore
are stplained more satisfactorily than hitherto from the
point of view of transformations taking place in the iron.
4) The results of the here described work-,can be applied
for selecting optimum tmperatures for the preparation and
Card 6/? processing of ores in the neighbourhood of critical points.
