ABSTRACT: In the present paper the investigation of the catalytic
oxidation -)f hydrocarbons is continued and the oxidation
kinetics of ramified hydrocarbons (in this case isobutane in
the presence of HBr) is investigated by means of NBr. This
reaction is very sensitive to the surface condition of the
reaction vessels. Thus molybdene-glass vessels covered with
a layer of boron oxides were used. The oxidation was carried
out an a vacuum unit under static conditions. A figure shows
the unit used. The way in which the reaction products were
removed from the vessels is described. The peroxides obtained
in the reaction were identified polarographically (peroxides
of tertiary butyl, tertiary butyl alcohol, and acetone). Very
definite stages were observed in the reaction process. In the
Card 1/2 first stage isobutane is mainly oxidized so that it forms the

hydroperoxide of tertiary butyl; in the second stage the
oxygen consumption drops and the reaction takes place via
the formation of the hydroperoxide of butyl alcohol and the
decomposition of the peroxide while acetone is formed. These
facto were obtained by means of the determination of the
yields under varying reaction conditions (changes in the
concentration of initial materials) (Figs 3,4). The summary
reaction process is represented by the following equations:

ABSTRACT: A short t--me ago it was found (Refs 1-3) that on the oxidat-,On
of n-de,^ane (1) several changes take place in the laurates and
stearates of manganese and cobalt, A valence change of the
catalyzer takes place which causes its falling out and be,~ominE

of the accumulation of colored intermediate products of these
catalyzers are investigated. The oxidation of (I) took place in
a way already described,, The samples were examined in the wave

oxidation of (I), whereas the activation energy of the further
reduction of the intermediate compound is 16.1 kcal. The
absorption coefficients of the intermediate compound were
determined in sumene (since it is simpler than in (T) ) and at
400 m 4, the value 780 1/g-mol cm was found. Beer's (Ber) law
is followed up to a catalyzer concentration of 0,016 mt/Fig 7).
Tests With (I), tetralin, and cumene showed that the absorption
coefficient of the intermediate compound obviously does not
depend too much on the hydrocarbon to be oxidized (Fig 6).The
kinetic of the accumulation of colored intermediate
products show an initial acceleration (Pig 7). At the curve
maximum cumene and tetralin show a complete transition of
manganese stearateto alli-her valence stage and (I) a 30~5
transition only. There are 8 figures and 4 Soviet references,

TITLE: Kinetic Laws for Autocatalytic Reactions in Open Systems
PERIODICAL: Doklady Akademii. nauk SSSR, 1959, Vol 128, Nr 4,
PP 755-758 (USSR)
ABSTRACT: In chemical technology, the continuous process of reactions
is attempted more and more, i.e. of reactions in open systems.
While the kinetics of simple processes had already been in-
vestigated (Refs 2-4), no data are available on autocatalytic
processes. Therefore, the continuous oxidation of cyclo-
hexanone to adipic acid by oxygen at 1300 was studied. The
apparatus used permitted the automatic maintenance of the
inflow of raw material and of the outflow of the reaction
products. The term of "specific velocity" v is defined as
the volume of the liquid initial component supplied to the
unit of volume of the reaction vessel in the unit of time.
The value I indicatas the avera,-,e duration of stay of the
v
liquid in the reaction vessel. The content of hydrogen per-
Card 1/3 oxide, adipic acid, and CO 2 in the reaction product is

determined for different v. In the continuous process, a
stationary state appears, i.e. the reaction rate and the
discharge of the end product are in an equilibrium relation
to each other. Figure 1 shows the dependence of the equi-
librium concentration of adipic acid on v. In the transition
from the periodic process to the continuous one, it is of
no importance in which phase of reaction this transition
takes place since the equilibrium concentration ig formed
corresponding to v, irrespective of the oxidation degree
attained. While for simple reactions the rate rises mono-
tonously with v, there i-s a different dependence for auto-
catalytic reactions since not only the concentration of the
initial. product but also that of the resulting intermediate
product (hydrogen peroxide) is decisive. Figure 3 shows that
the reaction rate passes a maximum at a certain v; if v keeps
on rising, the reaction rate falls since the concentration
of the hydrogen peroxide becomes lower. The equation for the
maximum reaction rate Is written down. It is pointed out
that in the continuous process, in comparison with the
Card 2/3 periodic process, a smaller amount of burning to CO 2 and H20

occurs because the reaction products remain in the
reaction zone for a shorter period. There are 3 figures

TEXT: The oxidation mentioned in the title consists of two distinct
macroscopic stages separated in time (oxidation of isobutane with oxygen
on tert. butyl hydroperoxide, and decomposition of hydroperoxide and its
-eaction with the initial hydrocarbon).
The differential-calorimetric
method suggested by A. A. Kovallskiy (Ref. 5) was used for the atudy of
the oxidation kinetics, and furthAr evidence was found for the two-otage
reaction course. and the part played by the surface in the macroscopic
stages of this reaction was defined. The reaction was studied in a static
vacuum system. A Mo-glass reaction vessel was washed out with a boric acid
solution for surface stabilization (Ref. 6). The differential thermocouple

0.44-mm quartz capillaries. The junction for the measurement of temperatur"-
in the central zone was fixed in the central capillary, and the junction
for the measurement of the wall temperature was fixed on the vessel wall,
The heat flow between the temperatuie in the renter of the reaction
mixture and on the vessel wall was measured by a mirror galvanometer with
an accuracy of 2.8.10-9 a/'mm/m. The kinetic curves of the accumulation of
tert, butyl hydroperoxide and the heating curves of the reaction mixture
during the isobutane oxidation in the presence of HBr are shown in Fig.
while the temperature dependence (-,f 'Tmax (heating maximum) is illtistrated
in Fig. 2. The activation energy determined from the inclination of the
straight line is 16.8 kcal/mole, which Is in gocd agreement with the value
of 16.4 kcall/mole found earlier from the kinetic curves of the
accumulation of tert. butyl hydrcperoxide. Tests made by applying a KCI
layer first onto the reaction surface vessel and then onte the surfane
of the central capillary revealed that the heating of the react-ion mixture.

TITLE: Mechanism of chain ramifications during oxidation of methyl
ethyl ketone in liquid phase
PERIODICAL: Akademiya nauk SSSR. Doklady, v. 140, no. 2, 1961, 405-408
TEXT: The authors found that the degenerate chain ramification during
oxidation of methyl ethyl ketone (I) in liquid phase proceeds through the
decomposition into radicals of two intermediate compounds, keto hydro-
peroxide and diacetyl. (I) was oxidized with atmospheric oxygen in an
autoclave at 50 atm and 100-145'C. The oxidation products (acetic acid,
ethyl acetate, diacetyl, ethanol, peroxides, 00, and C02) were analyzed
chemically or by paper chromatography. From the course of the kinetic
curve for the (I) consumption (Fig. 1) it may be concluded that the oxida-
tion is a reaction of the first order. In fact, a complicated process
takes place, which is suggested by the chain reaction and the anomalously
low factor before the exponential function in the equation for the constant

of the reaction ratep k m 5.2-10 exp(11,200/RT) sec- . The chain
character of the process was proven by addition of a-naphthol (II) as
inhibitor. In the presence of (II), a noticeable induction period occurs,
the duration of which rises with increasing inhibitor concentration. The
rate of formation of chains during oxidation of (1)_gas determined from
the kinetics of inhibitor consumption: cio = 1.5-10 mole/liter-sec at
1450C. During the process, the rate of initiation rises as compared with
% due to the formation of degenerate ramifications. The rate of
initiation during the reaction was determined by measuring the consumption
of inhibitor (II) freshly supplied at different time interv4~s. Fig. 3
shows that the oxidation of (I) proceeds like a chain reaction. The rate
of initiation, however, rises to double its value only. For ~he rateci of
oxidation of (T), it is written down: ej - (k2/V-k5) [RCOR,](,),' /2. An
increase.of the reaction rate 0 to double its value changes the initiation
rate L), 1/2 by the 1.3-fold only, which leads to a linear dependence of the
reaction rate on the concentration of (1), i.e., to a reaction of the first
order. The rate of chain ramification during oxidation of (1) rises in
proportion with the accumulating amount of keto hydroperoxide only at the

beginning of the reaction. Later on, a higher total rate of formation of
radicals is observed than corresponds to the decomposition of keto
hydroperoxide into free radicals. This shows thatp besides keto hydro-
peroxide# other intermediates participate in the chain ramification
during oxidation of (1). The assumption of a cooperation of diacet~l
(formed in this reaction and readily decomposable into two radicals was
confirmed by an increasing rate of chain ramification on 'addition of
diacetyl. The dependence of the ramification rate on the total concentra-
tion of keto hydroperoxide and diaoetyl is calculated:

ketonei 1450C, 50 atm., ketone i benzene ratio w I j 1, 1 j 2, 1 t 3. In
both cases, an increase in benzene, which reduces the dielectric constant
of the medium, was found to alter the composition of reaction products.
With ethyl alcohol, the amount of products obtained from the bimolecular
reaction of peroxide radicals was 20% at I 1 3, and 80% in 'pure alcohol.
With methyl-ethyl ketone, (1 1 3) the reaction products had the same
composition as with oxidation in the gas phase. Differences in the oxida-
tion mechanisms of polar organic compounds in goo and liquid phases are
due to the rate of the reaction between the peroxide radical and the
oxidizing substance (bimolecular reaction), the dielectric constant of
the medium, and the formation of intermolecular hydrogen bonds. The bi-
molecular reaction between RO~ and the test material, is between two
dipoles and slows down as polarity decreases. Good agreement between
experimental and calculated dipole momenta confirms the structure assumed
for the activated complexes in the.case of methyl-ethyl ketone, but not
for ethyl alcohol. This shows that the reaction rate of ROi and ethyl
alcohol is not only dependent on the polarity of the medium but also on

the formation of intermolecular hydrogen bonds. It is not the individual
molecules (RH and RO~) which react, but aggregates consisting of five or
more particles linked by hydrogen bonds. There are 5 figures and

TEXT: A comparative study of the mechanism of oxidation of
methylethylketone in the liquid and gaseous states was undertaken
to elucidate the effect of polarity and*the al;sence of hydrogen
-the phase oxidation was,
bonding in oxi-dkrpe7d molecule--ri TYpip 41quid
studied :Cor--the first time. Both the~liquid and gaseous
oxidation were carried out at 1450C and 50 atm. The liquid
oxidation Was a complex chain reaction.imttating a first order
reaction. Individual stages of the roactions were studied by
adding a-naphthol at various times durtng the reaction, this
stopped the chain reactions and peemifted to characterize
the non-chain reactions. Diacetyl, ketchydroperoxide and
ethylacetate (intermediate oxidation ptoducts) undergo non-chain
decomposition, the hydroperoxide in this case decomposing much
more rapidly than hydrocarbon hydroper#xides. Diacetyl decomposes

at a higher rate than that calculated from the consumption of
a-naphthol which indicates that the branching reaction is not the
only decomposition process. Ethylacetate is decomposed by water
forming during the oxidation, acetic acid thus produced being a
part of the total acid formed. The remaindVr of the acid is
formed from the decomposition of diacetyl. Acetic acid is also
formed from ketohydroperoxide via diacetyl. In the gaseous phase
oxidation there is formation of formaldehyde, acetaldehyde,
acetone, formic acid, methyl acetate, methyl alcohol and CO,
whichare not produced in the liquid phase oxidation. Conversely,
the formation of ethylacetate and diacetyl decreases during the
gaseous oxidation. There is little difference however in the
formation of acetic acid. Comparing the rates of formation of
the oxidation products during the two types of oxidation, the
authors conclude that the specificity of the liquid phase oxidation
is due to the polarity of the oxidized subatancq. Comparison
with the oxidation of ethyl alcohol indicates that hydrogen bonds
also affect the mechanism of oxidation* The mechanism of chain
branching in the same for the liquid and gaseous oxidations which

and subsequently of decanol-5 having the same concentration were added,
then the stationary concentration C remained constant. The hydroperoxide

ABSTRACT: The consumption rate of two inhibitors (antioxidants)
of the fftenol and aromatic amine type in hydrocarbon oxidation has
been studied to clarify the mechanism of the synergistic effect of

an
azobieisobutyronitrilel d conducted at 70C. This oxidation
I Kas the advantage of being an "unbrandhad" chain reac-
tion. Changes in inhibitor concentration in the cou::se of oxida-
tion were deterfained spectrophotometrically by formation of an
azo dye from the inhibitor and added diazotized p-nitroaniline.
It was found that a single inhibitor iB spent at a rate equal to
one-half the initiation rate, indicating that one inhibitor mole-
cule reacts with two R02 free radicals. When the two inhibitors
are used together, consumption of Neozone D is slight until prac-
tically all of the phenol I is spent. Neozone D is subsequently
consumed at a rate close to the half-rate. , This amine-consump-
tion inhibition is observed at various ratios and total contents i
of the two inhibitors. The same inhibition was observed with other:
pairs of phenols and amines; e.g.. Neozone D with 2,6-di-tert-
butyl-4-methylphenol (Ionol) or with tetraisopropylphenolphthalein.'
Replacement of Neozone D with another amine, diphenylamine, also
resulted in considerable slowing of amine consumption in the presence
of the phenol. In an attempt to explain this phenomenon, the rate
constants of the reaction between inhibitor and RO free radicals
2

were determined by~the chemiluminescence quenching method (0. N.
Karpukhin, V. Ya. Shlyapintokh, N. V. Zolotdva, Izv. AN SSSR, OKhN,
1963, No. 10). It was clearly indicated that inhibition of amine
consumption in the presence of phenols in not caused by the dif-
ference in the vialues of the constants, i.e., in the effectiveness
of the inhibitor. It is assumed that a free radical formed by the
reaction of the amine with R02 radicals abstracts a hydrogen atom
from the phenol,thus restoring the amine. Hence, amine concentra-
tion changes only slightly until all of the phenol is consumed.
This assumption was confirmed experimentally by establishing that
diphenylamine accumulates during ethylbenzene oxidation inhibited
by Ionol and tetraphenylhydrazine. The latter is a source of
(C6H029 radicals which form diphenylaminefon reacting with Ionol
(by ebstracting Rn H atom from this phenol). Oxidation of the
RR,N free radicals does not occur, since the reaction rate with
Ionol is higher than the RiR2A oxidation rate. The results of
the study may also contribute to an understanding of the synergistic
effect of Inhibitor pairs at higher temperatures. Orig. art. has:

ABSTRACT: A sym
,from 11 to 14 Aprl-l.-Yhe sym-pos ium was dedicated to -Academician -N. N.
Semenov on the occasion of his 70th hirthday and 50th year of scientific
activity. Semenov himself made the opening address to some 500 Soviet
and foreign scientists by outlining Lhe history of development of his
theory of chain reactions and combustion processes and by discussing the
.theory of branched chain reactions, including the latest developments
wnich have resulted from experimental work at the Institute of Chcmica_~
_f~ ~si~s, AS US SR. A significant new contribution to the theory of
branching was made when Semonov introduced the idea that molecules in the
excited state participate in branchIng. Semenov also a4vanced a hypothe-
sis of the exciton mechanism to explain low-Leipperature". ipoly-merization in
the solid phase without activation Pnergy.

ABSTRACTs A relations'.ilp has been established between the occurrence
of synergies between two oxidation inhibitors-an aromatic anine (ASH)
and an alkylphenolA(PhOH) -and the structure of the alkylphenol. This
synergism Is assu:;~ to be due to a free-radicaltreaction of the two

The effect of phenols having different substituents ortho or par& to
the OH group, in conjunction with N-phanyl-B-naphthylanineq (Neozont 4)
was studied in the azebtalmobutyronitrile-initiated low-temperature
(60-700 oxidationiof ethylbensene,lby a chesiluminescenne technique &4
and by chemical analysis. It was sh6wn that the sypergion.occur in
the case of o,o'-dialkylphenole but not in the case of o-alkyl a:d
nonsubstituted phenols. This was attributed to the fact that the rste~
of &nine regeneration (reaction (2)) Increases with increasing PhOO
radical stabilityg which in turn increases with increasing steric
hindrance of the phenol's OH group. A relationship was also estab-
lished between the inhibitor effectiveness of the phenols [in the
absence of the amine) and their structure. The criterion of inhibitor
effectiveness used was the constant of*the'reaction of the phenol with
ROJ radicals, The activation energy of the reaction of 2,4,6-tri-
tert-butylphenol with ROi radicals was found to be 3.4 kcalluol. The
