Abstract: A separation and investigation of the tarry substances of Georgian,
Nebit dag, Tuymazin and Romashkin petroleum have been carried out.
First by dilution with a 40-fold volume of pentane were separated
the asphaltenes and the solution of tars and hydrocarbons was passed
through the adsorbent. The best adsorbent was found to be ASK silica-
gel of pakticle size 0.37-0.20 mm. Adsorbed tars were displaced

Abstract: successively with carbon tetrachloride, benzene, acetone and alcohol-
benzene mixture (1:1). The tar fractions thus obtained were char-
acterized according to elemental cMpcsition, molecular weight,
iodine number, acidity and luminescence. For a more thorough sepa-
ration of tar fractions they were separated by means of phenol. The
investigations showed that tars of different petroleum differ ap-
preciably from one another in quantitative ratios of the fractions
as well as in properties and elemental composition of the latter.
In the tars of all the investigated variet:~es of petroleum was ob-
served a regular decrease in carbon content and increase in the con-
tent of hydrogen., oxygen and sulfur as well as of the C:H ratio on
consecutive passing from first to last fraction. Regular changes
were observed also in the other investigated properties of the fxac-
tions which indicate an appreciable difference between tar fractions.
There are included color photographs of thr luminescence of paper
chromatographs of tar solutions and a detailed description is given
of the luminescence picture.

Resinous substances from the Romashkino crude and from the Gyurgyany crude
were taken for this study. The increase of the amount of acid and neutral saponi-
fiable substances is directly proportional to the increase of the amount of hetero-
atoms they contain (0,S,N). All resinous substances are characterized by consi-
derable surface activity. They can be separated into tractions of increasing
surface activity with the aid of a series of solvents kith increasing dielectric
constants. The differentiation of resinous fractions can be improved by the in-
clusion of cyclohexane as a solvent. The molecular, surface, and polarization
characteristics are used for the differentiation of fractions which show similar
results in chemical analysis. There are 2 tables, 9 figures and 7 references of
which 5 are Soviet and 2 English.

TITLE: On the Poesibility of Producing Polymeric Materials With
Semiconductor Properties From Polyacrylnitrile
PERIODICALs Doklady Akademii nauk SSSR9 1959, Vol 128,, Nr 2, PP 312-315 (USSR)
ABSTRACT: It is difficult to produce organic substances with electronic
conductivity since the admitted zones, if they develop at all,
are narrow herep whereas the forbidden zones are very wide.
This width is so considerable that no electron excitation is
caused at temperatures at which the substance concerned is not
yet decomposed. The'semiconductor properties of the substances
described in pi4blioations are usually connected with existing
condensed aromatie rings and nitrogen atoms (Ref 1). Current
carriers are bound to devAi~-p comparatively easily in polymers
with double bonds, especially with conjugated double bonds,
furthermore with atoms in the chain which have electrons on the
outer levels that do not take part in the chemical bond (8.g.
nitrogen atoms). The aleotron dispersion in the latter is

structure. The neceesaxy regularity degree can be approximately
estimated from the length of the free path of the electron in
the semiconducto-r, furthermore from the length of the C-C-bondsp
the length of the manameric member, andthe length of the
electron wave. It was found that one polymeric molecule is
sufficient in the main chain of which exists no branching with
more than 12 oarbon atoms Per 35 monomerke members. This holds
in the case of a fiber with maximum elo.ngat--'-rjn in which the
polymeria moleaules are arranged in the direr;ticn of the
current. Then, no dispersion on the structural irregularities
is to be expected. The production of polymers with such a
degree of regularity'is well possible today. An investigation
of the products of thermal tranafo=mation of polyacrylnitrile
is interesting from the above standpoint. The view of the
transformations proceeding here is expla:tned by a scheme.
Table 1 gives the results of measurement of the paramagnetic
electron resonance of the polymers at room temperature. The
method and the device used for this purpose are described in
reference 3. From the data given in table 1 it follaws that:
