and A. A K val'skiy. Zh. fiz. khimii, 1946, Vol ZO, 3025) has
been applied to measurements under conditions of laminar gas

Title Part Played by Surface in Reaction of Thermal Decomposition
of Ozone.
Orig Pub Dokl. AN SSSR, 1956, 110, No 1, 105-107
Abstract The decomposition of ozone (0 ) in a flow at atmospheric pres-
Q of divided calorimetric measure-
sure was studied by the meth
meats. The decrease of warming up Was observed with the in-
crease of the radius of the central capillary containing one
of the junctions of the differential thermocouple. In authors'
opinion, this suggests that the decomposition of 0 includes
an endothermic stage Of 03, dissociation taking p2ce on the
vessel walls. The next stage seems to be a homologous exo-
thermal reaction, in which the atoms produced on the surface
take part. The earlier proposed mechanism (RZhnim, 1955,
36907) consisting in a homologous dissociation of 03 molecules
and a following recombination of 0 atoms on the vessel sur-
face is rejected.

TME: The Formation of Hydrogen Peroxide in the Oxidation of Formaldowe
((Ybrazovaniye perekisi vodcroda pri okialenii formalldegida)
PZMDICAL: Zhunl&l F1zich"k0Y Kh' m4 1, 1957, Vol. 31, Nr 12, pp. 2649-2655 ( USSR)
ABSTRACT: It me tried hero to identify the peroxides developing with the oxi-
dation of CH20. It was stated that under the existing test-oonditions,
the Wrogen peradde is the primary peroxide compound , whersaa the
formation of dioxymetlaylperoxiae represents a secondary process. The
latter took place chiefly outside the reaction vessel an a consequence
of the interchange Of H 02 and CH20. The radiation method was applied
bare. The reaction me investigated in the mixture of CH20 and air at
atmospheric pressure and at a temperature of the order of 5000 0. The
fonowing results were obtaineds the content of peroxide in the re-
action products depends to a great extent not only on the taiVerature
and velocity of flow in the vessel, but also on the state of the sur-
face of the reaction vessel. The greatest quantities of peroxide
were obtained in the new vessel on the first working day. This holds
for reaction vessels, of glass and quartz. In some cases the content

peroxide in unknown in literature. The fresh solution from the ab-
noiter showed an insignificant acidity. When the solution was either
left or heated, the acidity Increased, but the content of peroxides
end CH20 declined. The heating of the solution me accompanied by a
precipitation of hydrogen. For completely decomposing the peroxides
it was sufficient to boll the solution within 10 to 15 minutes. The
nature of the acdd developing when boiling the solution -mw analyti-
cally determined af ter the reaction with ZnO. The investigation of
the kinetics of reaction of peroxide oampounds with NJ In the acid-
medium showed that the velocity of J2 precipitation depends largely
on the time between the obtaining of the solution in the absorber
and the mcment where NJ Is adaed to the same. That is to say, the
solution "ages" in any extent. The keeping of the solution itself at
.50 0 deoslerates the reaction with potassium iodide remarkably. The
fact that an aging lasting more than one hour of the solution exer-
oiBes no noticeable influence on the reduction of the J precipita-
tion is characteristic. Investigation of the role playJ by *drIDgen
peroxide at the reaction of GH2p-oxidation clearly showed that at
1050 0 and a stay of from 20 to 25 secionas of the gas mixture in the
Card 213 reactor, the reaction fully took place between CH20 and B202. The

teats further showed that HA21 which forms one of the products at
the oxidation of forma2deWe, has no affect on the proper reaction
of the oxidation within the range of from 1300 to 4500 0. At lower
taVeratures of about 1000 C most likely a process takes place wtdch
has nothing to do with the reaction of oxidation mid which leads to

ADSTRACTs In the authors' previous works the reaction of the forming of nitrogen
oxide was Investigated by high adiabatic compression. It was also
possitle to obtain jyielft of up to 1% from pure air within some ten
thousandths parts of a sseqmd2 at a coupression of up tb 700 and a
pressure of 80con - 9000 kg/cm . By dilution of the mixture with argon,
by which higher temperatures were attaftedo or by the addition of
fuels (methane, H , CO), the authors were able to increase the nitrogen
yield up to more Kam j % by increasing the temperature by means of
combustion. Uuder these circumstances the production of HCN is also
possible and was studied an this occasion. Theraodynx;mio consider-
ations point to the face that with a rise of temperature the equilibrium
is shifted In the came of this reaction In favor of the formation of
HCN, which In similar to vluk-t Is the case with the formation of 150.

and acetylene, was inrestigv~te4, In the case of methane there was

) The addition of argon also here leads
pressure of 5000-9000 kg,
to an Increase of the yield of HCN up to 4 %. The shape of the ex-
perimental curves deserves special intereatt They are characterized
by transition to saturation. Apparently the oonstant HCN yield is
to be explained by the cobling regime, in which connection a sort
of "hardening" takes place. Therefore, the HCN quantity, which is
actually proved by means of the reaction products, need not corre-
spond to that quantity which was obtained by experiments carried out
at maximum temperatures, but It can be much smaller. Cooling of
reaction products forms an integral part of the adiabatic cycle,
By this It is possible to explain the occurrence of a horizontal
section of the prves (illustration 1) at a pressure of about

ABSTRACT: The authors employed a method suggested already earlier 'Ref 1).
The methane used contained 1-2% of higher hydrocarbons. The
most interesting part of the adiabatic cycle, within which the
pressure increases to some hundreds and thousands of kg/cm2,
lasts only some ten-thousandths of a second. The velocity of
the temperature change of the compressed gas is therefore also
10 6_ 107 degree/second, so that a rapid drop of temperature in
the expansion of chemically active gas mixtures leads to a
high degree of hardening (Ref 2); thus, the reaction may be
fixed at an intermediate stage. In the paper by M. S. Furman
and D. S. Tsiklis (Ref 7) the formation of formaldehyde in an
Card 1/3 adiabatic compression of methane-oxygen mixtures was qualita-

tively determined. The present experiments show that the charac-
ter of the reaction of the mixture depends first of all on the
oxygen content. Mixtures with more than 15% 02 ignite under the
deposition of soot. It is characteristic that the ignition does
not take place at the maximum pressure but a little later when
the mixture has expanded. Only with an oxygen content of less
than 15% was it possible to interrupt the reduction in order
to obtain an intermediate product. The reaction products of
the compression have an unpleasant,sharp smell and contair
formaldehyde as well as other intermediate products which form
an intense fog with air. At a low compression (300-350 ke/cm2)
and a low content of formaldehyde this formation of fog is not
observed. In mixtures of natural gas and oxygen the formaldehyde
formation begins at lower compressions than in pure methane, due
to the increase of the oxygen content. The maximum content of
formaldehyde (2, ea) is obtained at an oxygen content of 6 and
9%, and at a pressure of about 3000 kg/cm 2; it remains constant

ABSTRACT: The problem of methane oxidation, very important in view of chemical
utilization of natural gases, was dealt with in many investigations,
including those of Medvedev /Refs 25, 2g and D.M. Rudkovskiy. The
present article describes some results of laboratory studies in ob-
taining formaldehyde by means of methane oxidation catalyzed by nitro-
gen oxides. The following research workers of the VNIIGAZ UNP parti-
cipated in individual phases of these studies: S.A. Anisonjan, S.Ya.
Beyder, and N.I. Vinnikova, and of the Giprokauchuk MKhP: A.S.Zhadayev,
N.N. Chernov and U.N. Shendrik. The methane oxidation was carried out
under jet conditions at a pressure of the gas mixture near the atmo-
spheric one and at temperatures of 600 to 8000C. Various conditions of
experimentation were tried out in order to find the optimum ones, and
Card 1/2 the results were as follows: 1. The treatment of the inner surface of

a vessel, in which reactions take place, with K2B407 increases and
stabilizes the yield of formaldehyde and reduces the reaction tempera-
ture by 80 or 100 0C; 2. The relative yield of formaldehyde (CH20 : NO)
amounts to 10 to 12 molecules per one molecule of the catalyst; 3. The
optimum composition of the methane-air mixture was found to be 1 : 2;
4. The optimum temperature of the reaction is about 1000 C; 5. The stabi
run of the reaction is possible in metal vessels; 6. The laboratory
results were confirmed by experiments carried out in a pilot instal-
lation with a capacity of 13 m3/hr of gas-air mixture. There are 7

ABSTRACT: The preparation of formaldehyde in reaction vessels installed in line
and also by the method of recirculation is investigated here. In one
series, the gas-air mixture of 33.3% CH4, 66.6% air and 0.1% NO vias
passed through reaction vessels. The formaldehyde was separated by %;a-~=_r
in absorbers. It has been shown that under these conditions 7.4% of
methane is oxidized to formaldehyde and 9 - 1N, to carbon monoxide. In
the closed circulation method the mixture was passed many times through
the reaction vessel. After 8 cycles 18.5% of methane is oxidized to
formaldehyde and 19.7% to carbon monoxide. An additional supply of air
or oxygen increases the yield to 32%. The yield of formaldehyde per
1 molecule of NO is 20 and even 30 molecules at 550 and 5900C. In the
continuous circulation method the mixture is continuously supplied with
Card 1/2 fresh gas. The temperature varies from 565 - 6800C. NO was supplied

to keep the cor--er.tration at 0.1 volume %. After 10 circulations 21%
of methane is convexted to formaldehyde. The losses of NO due to ab-

ABSTRACT: The physical importance of chilling is shown by the example
of the synthesis of nitrogen oxide and the role of chilling
rate of the combustion products is pointed out, In the re-
action 0 + N 2 NO - 43 kcal (1) in the presence of an

excess quantity of oxygen a temperature rise will favor the
reaction (in the first phase) towards the right, whereas in
the case of chilling (in the second phase) the decomposition
reaction is favored. If in the case of high temperatures the
reaction rate (RR) is sufficiently high, the VO-concentration
approaches the equilibrium value. Chilling in the second phase
of the process (Fig 1) will lead to a still greater deviation
of the NO-concentration from the equilibrium value in order
Card 1/2 to remain constant at a temperature Ti. In publications this

phenomenon is called chilling. In order to obtain a precise
explanation of the conditions of cooling the connection be-
tween the (RR) of the NO-decomposition and the rate of varia-
tion of the equilibrium concentration are taken into account
at different stages of cooling, and the two entirely different
processes of reaction are determined. The transition from
one reaction are determined. The transition from one reaction
phase into the other is denoted by several critical values
of chilling rate and determines the phase of chilling. There

ABSTRACT: In continuation of a previous puper (Ref 1) a number of data
from publications on investigations of the nitrogen oxide
synthesis under various experimental conditions is explained
in this paper. The paper which contains the corresponding
diagrams and tables is divided into the following chapters:
natural cooling of the reaction products in closed reaction
vessels. Experiments in apparatus with an intensive cooling.
Experiments in adiabatic apparatus. Determinations in flov
apparatus. It was found that all data which were obtained under
most different conditions may be considered from one view-
point and therefore determinations may be made with experimen-
tal data from two completely different conditions of reaction.
In one case the rate of the direct synthesis reaction is in-
sufficient, in the other, the rate of cooling of the reaction
Card 1/2 products is low. In the experimental data investigated the

NO-yield is determined mainly by the rate of cooling. Ex-
periments which took place under an intensive cooling were
successful only in two cases: in the method of membrane de-
struction (Ref 12) and in experiments on an adiabatic appara-
tus (Ref 15) where a strong increaseof the rate of cooling
and a corresponding increase in the NO-yield was attained.

TITLE: A Study of the Oxidation and DecGmposition Reactions of
Formaldehyde at High Temperatures
PERIODICAL; Zhurnal fizicheskoy khimiif 1959v Vol 33, Nr 8, pp 1695-1700 (USSR)
ABSTRACT: In order to develop the technology of a methane oxidation to
formaldehyde (I) it was necessary to study the stability of (I)
in the reaction gas (Refs 1-2). Since the corresponding data found
in publications refer to relatively low temperatures and 3a3ger omhxt
times, and thus did not suffice for the desirod purposes, special
experiments ivere carried out in the preselit case. The oxidation
and decomposition reactions of (1) were studied within the
temperature range of 500-8500 at a contact time of 0.3 seconds
and atmospheric pressure. The studies were carried out in a flaw
unit (Fig 1). The (I) concentration in the initial gas mixtures
was I fa by volume throughout. The oxidation reaction was studied
with a mixture air: (I) - 99 : I in an empty reaction vessel as
well as in one fillsd with packing. It was found that the
oxidation rate largely depends on the surface properties of the
Card 1/2 walls of the reaction vessel as well as on the Sfi value, Washing

out the reaction vessel with a 2 % K 24'7- solution, and filling
it with packings, resulted in a considerable retardation of the
oxidation reaction of (I). NO additions (0.1 %) to the initial
gas mixture greatly accelerates thG reaction in the presence of
oxygen. The decomposition reaction of (I) was studied in mixtures
CH4 . (I) -; 99 ; i in the absence of oxygen, and it was found
that there is no dependenoe of the decomposition rate (DR) upon
the properties of the surface of the reaction vessel wall, or
the S/V value. NO additions (up to 0.8 %) did not show any marked
effect upon the (DR) either. There are 7 figures and
6 references, 4 of which are Soviet.

Publications on formaldehyde oxidation indicate the insufficient
investigation of this reaction. Comparison of the values of ac-
tivation energy obtained so far (Table 11 shows that the re-
sults are unsatisfactorily reproducible, which obviously is
due to the effect of heterogeneous factors. The latter and
especially the effect of the surface condition of the reaction
vessel were investigated here. Experiments were made under dy-
namic (Ref 1) and static conditions, and for some series of ex-
periment the authors also used the method of separate calori-
metrio measurement (Ref 11), The first experiments by the latter
method showed that the reaction rate was greatly dependent on
the surface condition (Fig 1). strong catalytic effects were
produced by coating the glass surface of the reaction vesoal
with PbO, while oxidation was Inhibited by treatment with

formaldehyde is oxidized without self-acceleration, CO 2' H20 and
CO being the main products. Kinetic curves obtained at 377-550 C
under static and dynamic experimental conditions had no period
of induction (Figs 3,4). The activation energy calculated from
the data listed in table 2 amounted to 50 kcal. Experiments made
with nontreated glass- and quartz vessels showed a distinct
period of induction -together with the formation of new reaction
products: H 202' (CH20H)202' HCOOH and R2 . Activation energy was
here 26 kcal, which is in accordanoe with publications. The sur-
face of the reaction vessel consequently determines the reaction
rate and the composition of the reaction productso In conclusion,
the authors thank Professor A. B. galbandyan for a discussion.

The temperature coefficients of the reaction rates were different in each
case. The obversable reaction acceleration was found to be due to cata-
lysis by hydrogen peroxide. Also the effect of R 202on the inflamation
limit of an air-formaldehyde mixture was studied. The experiments showed
that it is lowered by an addition of H 202' All of the CO was oxidized to

Reaction (3) stimulates the other ones in an increasing manner since it
leads to formation of H 202* Two types of interaction of hydrogen peroxide
are assumed to occur. According to the one, it would act directly upon

At more than 3000C, however, the acid was not detectable. At higher temper-
atures the following process is assumed to take places
CH20 + H2 02-> 2 H20 + CO, which increases the oxidation rate. According
to the other variant, H 202 is assumed to decompose into its radicalst

TITLEt A New Boride Phase in the System Berylliu A - Boron-1
PERIODICAL: Zhurnal neorganicheskoy khimii, 1960, Vol. 5, No. 8,
pp. 1783-1787
TEXT:. In 1955 the authors published data on the phase composition of
beryllium borides (Refs. 19 2). Besides the cubic a-phase (Be B), P-phase
BOB 29 and y-phase BeB6' they had also determined a new 6-phasi richer
in Be which develops at 1000 0C during the sintering of a mixture of
pulverized boron and pulverized beryllium containing more than 70 atom%
of Be. The present paper reports on the investigation of composition
and properties of this 6-phase. Mixtures of B- and Be powder were produced
in the following ratios: Be s B ranging from 9 : 1 -to 2 : 1, and they were
radiographically examirsed (Table 1). Single crystals of the 6-phase
(Fig. ) were obtain*4 after 100 h of continuoue heating in evaouated quartz
ampule. Data of the radiographic inypatigallarl-of these crystals are given

are tetragons with the lattice constants a - 3.362 + 0.002 kX,

(Tables 39 4)- On the basis of these data, the following reaction equations
are given:

tetraboranes is only caused by the polymerization of BH 5* Since the reac-
tion between,BH 3 and water is intensive, no more than 8% of borane develop,
calculated with respect to the total amount of boron. Be 5B still is the Ll~
boride yielding the maximum amounts of borane, since Be 2B only develops
2% of boranes. There are 4 figures, I table, and 6 Soviet references.

on BeO plates and heated In a Silit furnace at 1,000 and 1,2000C with free
access of air. Borides which are rich in beryllium (Be B Be2B) are the
least resistant against scale formation; borldes rich rnboron (Be% " BeB
Be%) are the most resistant. The structure of the phases which are rich
boron is not yet deciphered, but it can be assumed that complex three-
dimensional boron skeletons are present in them, like those in hexaborides
of the Pie% type. These boron skeletons apparently cause the high chemical
resistance of beryllium borides with high boron content. The beryllium
borldes with the highest chemical resistance, however. are iftferior in this

mpeot to the borides of other metals. The Be borides were also treated
with nitrogen containing less than 0.01% 02. A complete analogy with the
action of oxygen can be observed, i.e-_ of Be
borldes increases with the boran oontent in them. During nitration beryllium
nitride Is formed. At temperatures of up to 1,2DOOC boron nitride could not
be d1scover*d by roentgenographic analysis. For studying the interaction of
beryllium borldes with carbon, boride powders were mixed with 25 weight % of
carbon and heated in briquetted form in an argon atmosphere. At temperatures
of 9D0 - 1,300oC Be C Is formed which proves that the affinity of beryllium
