ABSTRAM The present paper furnishes a solution of the problem of the
spatial steady distribution of tho forming heterogeneous active
centers on the assumption, that they are destroyed in the case
of mutual collisions on the surface and in the iAterior (i.9. in
the case of quadzetto stripping of the chains). 'his problem
arises *.g. in the came of a mixture of hydrogen with chlorine
without admixtures of oxygen. Lot the velocity of heterogeneous
generation bf much greater than the velocity of the homogeneous

The solution of this differential equation can be represents& by

ABS)TRACTs Two viewe are represented in publications on the oxidation of
hydrocarbons in regard to the nature of the "cold flame"
phenomenon. M. B. Neyman (Ref 1) explains this phenomenon in
terms of the explosive decomposition of organic peroxides,
while Pease (Ref 2) and Norrish (Refs 3 and 4) explain it as a
result of the thermal instability of the reacting system. The
authors suggest a new mechanism, He holds that the peroxide
radical reacts in one of two possible ways: either with the
initial hydrocarbon (RO; + RH -ROOH + R*), or through molec-
ular decomposition (RO; --RICHO + RIIO*). The second reaction
becomes predominant with an increase in temperature. To explain
this phenomenon an idea of N. N. Semenov (Ref 5) was used. This

zero with respect to b6p. Then the extreme yields of the
stable intermediate product are investigated in a complicated
chain reaction. The maximum yield of CH3CHO suffers no
systematic modification in the case of concentration changes
of the acti7q centres in the reaction system. In the case
of the mixture 2C H the yield of CH 0 becomes a function

of the reaction conditions: the conditions leading to the

these experimenta are illustrated on a diagram and demonstrate
that the yield of C1120 depends on the state of the surface
of tho motion containor. Thoroforep yield of C11 20 tit given
conditions of the oxidation of C11 has no maximum, i.e. ve-
locity of molecular consumption Of CH 0 is of the same order
of magnitude as with the consumption In the chain reaction.
The dependence of the yield of CH 20 on the nature of the
surface of the reaction container observed here may have two
reasonst 1) Destruction of the active centers on the surface
of the reaction container takes place in the kinetic or dif-
fusion-kinetic range. 2) Heterogeneous reaction of the con-
sumption of CH 20 takes place in the kinetic or diffusion-ki-
netic range. A dilution of the reaction compound with nitro-
gen renders difficult the diffusion of the radicals and
CH20 molecules to the wall and therefore is bound to increase
the yield of CH 20. The admixture of materials which can
produce active centers to the reaction compound is equally
bound to increase the yield of CH 0. A diagram illustrates
the results of tbeexperiments on ihe oxidation of methane

an increase of the 140 -content in the compound from 0 to
0,2 - 0,3 % increases the yield of CH20 by 4 to 8 times. At
the same time a strong increase of oxidation velocity is
observed. With sufficiently high concentration of the active
centers in the reaction system the yield of the stable in-
termediary product reaches the maximum value. Variation of
the concentration of the initiator exerts strong influence
on the oxidation velocity, however, practically does not in-
fluence at all the yield of CH20- All results found here
show among others the followings In the case of a not in-
itiated oxidation of methane formaldehyde is consumed mole-
cularly and the velocity of this consumption has the same
order of magnitude as consumption in chain reaction. There

PERIODICAL: Doklady Akademii Nauk SSSR, 1958, Vol- 119, fir 3, Pp. 520-522

ABSTRACT: I oharacteristical peculiarity of the,oxidation of the hydro-
carbons is the so eglled negative temperature coefficient in
a certain temperature range. This negative temperature range
has a strong influence upon the kinetics of the slow oxidat-
ion and upon the character of the self-ignition of the hydro-
carbons. The present theories (references 6112,13,14) actually
do not explain the phenomena of the negative temperature co-
efficient. This work investigates on the basis of the theory
of the degenerate ramification by N. N. Semenov the negative
temperature coefficient as a result of the competition of the
elementary processes, which are participating in a composed
chain reaction. At low temperatures the Qxidation of the hy-
drocarbons goes on passing through superoxide radicals, which
form after the reaction R + 02 --;%l ROO. This process has a low
Card 1A steric factor (1o-3 to lo-4) and a low activation energy

(2 to 4 great calories/mol). The elementary process of the
d~generate'ramification can be represented, after B. Llyuis
and G. Ellbe (reference 13) as well as after V. V. Voyevodskiy
and V. I. Vedeneyev(reforence 16), as result of the interact-
ion of the superoxide radical with a stable intermediary pro-
duct (a. g. with aldehyde) t ROO + R' CHO ----) HO + OR + R, Co.
By this reaction 3 new active centers form from a radical.The
reaction ROO RI CHO + R"O takes place with previous ino-
merization of the superoxide radical and therefore It has a
high activation energy (2o great oalories/mol). The competit-
ion of the two above given reactions causes the maximum in the
dependence of the reaction velocity on the temperature. At
low temperatures the superoxide radical must react according
to the bimolecular reaction. From a certain temperature pn-
wards, however, the monomolecular continuation reaction, which
above is given in the second place, predominates, by which
the oxidation velocity is decreased. The destruction of the
active centers essentially depends on the destruction of the
radicals R. With increasing temperature the probability of the
ramification decreases and on the other aide the steady con-
centration of the radicals ROO deoreaeoef so that the limiting
Card 2/4 process is the retLotion R + 02 -4 ROO. Therofore the oxidation

velocity of the hydrocarbons rapidly decreases with increasing
temperature. On the base .f this simplified oxidation scheme
an expression for the re4ution velocity is written down. The
velocity of the oxidation of a hydrocarbon passes a maximum
with increasing temperature. The author also solved the foll-
owing inversion problemi Given are the values of the ratio of
certain parameters and of the difference of the activation
energy of the elementary reactions. The steric factor of
the reaction R + 02 -4 ROO is to be computed, so that the re-
action velocity has its maximum at the temperature of 400OC-
The concerning numerical data are given here. The generalized
scheme of the oxidation of the hydrocarbons, suggested here,
thus leads to a maximum of the reaction velocity with regard to
the temperature. In case of further increase of the temper-
ature the consideration of the reaction RCHO + 02 -4 RCO +
+ 1102leads to an increase of the reaction velocity.

-
including those of Medvedev ZR
efs 25, 2f 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 M3F parti-
cipated in individual phases of these studies: S.A. Antsonyan, S.Ya.
Beyder, and N.I. Vinnikovap and of the Giprokauchuk MXhPt A.S.Zhadayev,
N.N. Chernov and M.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

stabilizes the yield of formaldehyde and reduces the reaction tempera-
ture by 80 or 100OC; 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 stable
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

A great part ot' the presented information is apparently taken from the Symposium
on Macrochernistry in Canada, 1961. Polymers of formaldehyde are known since thadr
discovery by A.M. Butlerov. Two types - polyoxialdehydes and polyoximethyleries
can be noted. Ifigh molecular weight polyoximethylene, i.e., poly t'ormaldchydo,

2) nz ccerai-acetal; or 3) by partial condensation. The monomer should contain

The latter is not con*umed during polymerization, i.e., active centers ave not
lost. Tiie effect of H20, CH
I CH30H, HCOOH, _3COOH, (CH3CO)20, CO, C02. and other
substances on rate and degree of polymerization was investigated expericXrtally.
In contrast to the OH ions the HCO3 and HCOO ions do not influence the polyme-
rization of formaldehyde. thus, in principle, a regulation of the process and
reproduction of polyformaldehyde with any desired molecular weight is possible.
The stability of para- formaldehyde against heat and oxidation depends only on the
nature of the end-group of the chain. The present authors demonstrate that at
thermal destruction also processes of chain transfer to the polymv are of im-
portance as well as to the evolving monomer formaldehyde, simultaneously with
.generation, growth and rupture of chains. Studies of the kinetics of thermal
destruction of polymers with CH and OCOCH3 end-radicals showed that the different
rato of doatruction depends upon tho difforont activation anargy. It Vinn pro.."Id
experim,ntally that oxygen increasea sharply the destruction rate, rind decivnser,
even more the molecular weight. However, the molecular weight of acetylized
polymer decreases much slower than !that of the non-stabilized polymer. This In-

ABSTRACT: In order to clarify the degree to which the reaction proceeds via an
ionic mechanism, the kinetics of thet radiation polymerization of isobutylene over
a temperature range of -40 to -196C were investigated. With respect to low-
t (F~erature radiation polymerization, the following conclusions could be drawn:
The independence of the polymerization yield of the Intensity of the dose indi-
cates a linear relationship between the polymerization rate and the radiation in-
tensity. The polymerization of isobuty-lene In the liquid phase is accelerated by
a decrease in temperature down to the freezing point of the monomer. The reaction
rate has an activation energy of 2.5 kcal/mol. in the solid phase, the reaction
rate has a normal temperature dependence with an aliparent activation energy of

+1.88 kcallmol. The maximum rate of polymerization Is obtained In the initial
stage of Irradiation and the process shows a tendency to become saturated as the
dose of radicition is increased. The molecular weight of the product-has a maxi-
mum value during the initial stage of irradiation, after which it drops rapidly
to a value of 15,000-20,000; thereafter it ' is essentially Independent of the dose.'

ABSrRACTs- Experiments were conduo ted using 0-382 gm of acetylated polyformal-
dehyde having a molecular weight of 0 .7*102, which was subjected to vapors of
85% formic acid in a current of oxygen or argon, or to the acid alone. The
kinetins of polyformaldehyde decomposition were recorded in an earlier paper by
.. At Dudinap L. V. Karmilova, No S. Yonikolopyan (Vy*sokomo1ek. soed., 5, 1160,
1963). It was found that at 220C tho rate oC thermooxidative decomposition of
polyformaldehyde in argon increases in proportion to the formic acid gas content
and that an almost double rate and volume of destruction take place in the prea-
once- of oxygen. Where samples of polyformaldehyde were reacted with liquid 65%
