was photogTaphed by a MOP camera. A more accurate picture was obtainod in an
x-ray goniometer KFOR. It was established on the basis of the x-ray pattern
analysis that praseodymium crystallized in the tetragonal rather than rhombohedral
0 ri
system and that its lattice parameters were a - b 3.74:t 0.01 A, c - 3.76:1 0.1 A.
The Lauo diffraction pattern of the samarium crystal showed that it had a diffrac-
tion symbol 2/mm. According to the Geller and Balla clioice of the coordinate axesP
the samarium crystal should have the third order axes, but the presence of such
axes in samarium was not sustained. However, the investigation showed the presence
of-clearly defined second-order axes and less clearly defined fourth-order axes.
It was. decided to take the edges of the perovskite cell as the direction of the
0
coordinate axes. For better results, the elementary cell constant 3.72 A was
doubled (in the plane perpendicular to the Z axis). The results proved that samar-
ium crystallized in the rhombic system with the lattice parameters a - b - '7.46 t
0.01; c - 7.43 t 0.01 AO. "Vie express our gratitude to V. A. loffe for the

ABSTRACT: The structure of prasoodymium and samarium, aluminates was studied in
order to verify the hypothesis stating that the perovskite-type structures underg6
transformations producing valuable plVsical properties. ?owders and single crystals
of the aluninates were prepared in Institut kliimii siliketov AN SSSR (Institute
of Silicate Chemistry, Acadewq of Sciences SSSR). Praseodymium and samarium
were studied previously by S. Geller and V. B. Balla (Acta Crystalog., 9, 1019,
1956) who referred the first aluminate to the rhomboliedral system with lattice
0
parameters: a 5.307 AjCX - 60-330, and the second to the rhombic system with

that the estimation defined by Mayorov is quite obviously
obnoxious. Summing up, it can be stated, that for the
estimation of the operation reliability in an arbitrary
sense the probability of a breakdown-free operation of the
regulator must be determined.

ABSTRACT: This publication JS a critical review of the paper by
A. A. Mayorov in Avtomatika i Telemekhanika, 1955, Vol. 16,
Nr, 5. The folloW4ng charges are brought up against the
author; An insufficient critical consideration of the
possibility to estimate the operation reliability of the
regulator in the state of the elaboration of a principal
scheme and a incorrect analysis of the operation reliability,
a wrong recommendation for the compilation of such
principal schemes of automatic regulator. It is shown, that
such schemes, which show no dependence of the operation
reliability on the technical execution, do not exist.
Furthermore it is pointed to the fact, that the optimum
criterium introduced by Mayorov gives no indication of the
probability of the occurrence of defects, because the
results are investigated in the case of the occurrence

t,as
Stages A and B do not determine the order of the reaction, since they
proceed faster than the decomposition; this'leaves stages C and D. The
kinetics of the process depends on whether stage C proceeds more rapidly
or as rapidly as stage D (first-order reaction) oron the contrary, D
proceeds more rapidly than C (zero-order reaction). The reaction is
faster on those spinels from which larger quantities of 0 2 are desorbed on
0
heating at 150 C in vacuo. Hence, the rate of N 20 decomposition depends on
the 0 2 mobility in the lattice of the spinel. There are 9 figures and
2 tables.

Of 02 on both spinels yielded the following values for the activation

studied by the method of the separate calorimetric procedure devised by
A4 ~. Kovallakiy and M. L. Bogoyavlenkaya (Ref. 9).The.reaction vessel
was 50 mm in diameter. A nichrome constantan differential thermocouple
was used for the measurement of the temperature difference. For both

was removed by absorption. The reaction kinetics obeys a monomolecular
law. The diagram of Fig. I with the coordinates log P = f(T) contains the
kinetic isothermal lines for the oxidation of the 2C3H6+902 mixture on
MnC0204 at 2500C. On the assumption of a monomolecular law, they have a
linear course, while the assumption of a square dependence leads-to
distortion. C02 molecules probably form complexes of the type C03 on the
catalyst surface. The specific rate constant KI calculated by a reaction
equation of the let order remains steady (Fig. 2). For a 2C3H6+902
oxidation at different temperatures, without removal of C02, the total
velocity may be calculated approximately with a reaction equation of the
2nd order. The specific constant KII, referred to surface unit of 1m2
catalyst, was found for each temperature. KII is a function of the
initial pressure of the mixture. The reaction rate was found to be
independent of the propylene concentration. An increase of the 02 content
from 0.096 to 0.433 mm Hg leads to an increase of the reaction rate. The
latter depends on the 02 concentration according to equation

pp. 860-863
TEXT: The present paper deals with the effect of the structure of spinels
CoMh204 and MnC0204 upon the catalytic action in propylene oxidation.
The catalytic activity was determined by measuring the oxidation rate of
propylene with 02 in a stoichiometric ratio of C3H6:02 = 2:9. The reaction
product contained C02 gas and water. The specific surface of the catalyst
was determined by the BET method from the equilibrium isotherms of
krypton sorption. The specific surface was 0.70 m2/g for CoMn204 and
0.25 m2/g for MnC0204. The reaction took place at a constant initial
mixture pressure of 0.450 mm Hg and in the temperature range of
2000 - 3500C. For purification, catalyst specimens were heated in vacuo

The optimum conditions of the catalyst modification by the

The results showed that the catalyst additives are progressively
reduced during the reaction and remo-ed from the silver catalyst

The authors assumed that a reduction of chlorine to HU takes place,
and that all reducing agents containing hydrogen are bound to cauae the
same effect. The experimental data of Table I (reaction with H 2t C2H 49
N2 + 5-3" i-C 3H7OH, N2 + 2j-4, C 2H 40, CO) confirm this. Only CO proved not
to reduce radioactivity. Further experiments were conducts 16 to determine
HC1 in the reaction products. Silver tablets containing lj~ were heated
with 02H4 to 3000C- A silver tablet cooled to 400C stood at a distance of
15 cm. After five hours of experimenting the silver plate had become
radioactive. The same effect was obtained with S34502L. Absorbing the

reaction products in water, containing methyl red, proved their acidity.
HCI was nephelometrically determined with AgNO . Measurement of radio-
activity in sections through the silver tablets proved that radioactivity
decreased in the entire volume of tablets, i.e. that no surface reaction
was concerned. The diffusion o 9 chlorine ions by silver was proven on a
silver single crystal with C13 . Fig. 2 shows the change of the radio-

shows the measurements of activation energy and the change in the
work function as a result of admixtures. The activation energy of
pure ZnO was very low (0.06 ev). The admixtures led to an in-
creaea of the activation energy as well as to a decrease of eleo-
trio conductivity. The electric resistance of the samples at 3500
decreased in the following order: ZnG+Li 20 >ZnO+ffa2O> ZnO+ZnSO4 )
> ZnO+ThO2> ZnO. From measurement of electric conductivity alone
the conclusion night have been drawn that all admixtures used are
acceptors and reduce the Fermi level to the level of the valence
band. Measurement of the work function, on the other handq shows
that Li and Na decrease the work function, and that ZnSO 4 and
ThO2increase it. The X-ray measurement carried out by
H. A. Shishakov et al. and M. Ya. Kus.Imerev revealed no changes
in the lattice constant of the modified zinc oxide, so that no
conclusions could be drawn as to the formation of solid solutions.

ABSTRACT: In many oases, the experimental data on the electric conductivity
of semiconductors contradict the conceptions of the position of
the Fermi level. The present paper is intended to characterize
the position of the Fermi level by the amount of the work func-
tion of the electron. For this purpose, the activation energy E
of electric conductivity and the change in the work function Y
of an electron after introduction of the admixtures Lip Na, Th,
and ZnSO 4 into ZnO are measured. For the purpose of introducing
Na and Li, the ZnO was saturated with the oxalates of these metals
and heated up to 450 - 5000. Thorium was precipitated from thorium

ABSTRACT: The authors refer to the publications dealing with the afore-
mentioned problem and quote G.K. Boreskov et al. (Ref 1). It
is noted that the effect of additions upon the isotope exchange
of oxygen on catalysts has not yet been studied. The present
paper is intended to close this gap. Silver and copper oxide
were chosen as typically oxidizing catalysts. The silver powder
was doped with AgCl ox AgJ, whose even distribution over the
surface was radiometrically checked by means of 0134 and J131.
CuO was doped with Or 20 39 Bi203? L120' or CuSO 4' The experiments

the signs of chargesdetermined: (II)~ Data with regard to the kinetics of
the oxidation process, available from publications and often paradox, can
probably be traced back to the dependence of the partial surface concentia-
tions of 02and C2H4 on the change of the work function The activation
energy of the oxidation of ethylene to ethylene oxide ought to change only
little in the modification of silver, since the surface concentration of
donor molecules is increased through an increase of T. These in turn level
the change off under the effect of metalloid additions. it was shown that
an increase of the work function reduced the activity of silver and raises
the selectivity of the process. Conclusively, the studies showed the
following: There is an interrelation between the work function of the
electron and the activity of the catalysts and the selectivity of the
oxidation processes of unsaturated hydrocarbons, The oxidation of hydro-
carbons proceeds over a number of parallel and successive staGes and,
according to the reaction mechanism, is differentially controlled by the
work function of the electron. The inhibition of a total oxidation with
an increase of the work function is characteristic of the reactions stult-d.

the activation energy and k 0 (factor of the exponential functions for the
reactions of the formation of acrolein and CO 2) depend on the work func-
tion For greater values of the work function, the activation energy of
the formation of acrolein is reduced and that of 00 2 increased. From the
dependence of the isotopic exchange on the work function V, the rate of
which increases for smaller values of 9, the controlling effect of the
work function on the surface concentration of 0 2 may be inferred The
selectivity of the acrolein synthesis is increased through the int-c'u-
tion of acceptor additions (S02-, Cl-) in CuO and reduced by that of

TEXT: In this paper the authors studiedthe oxidation of propylene on
cuprous oxide (Cu 20) and of ethylene o~ silver. The oxidation of propylem,
to acrolein on Cu 20 proceeds according toa paralleLLsuccessive scheme . A
step-by-step scheme is presumed: (I). On the basis of the change of the
work function of the eleptron during adsorption of reaction components on
Cu20, the sign of their charges could beestablished: Like most organic
substances, propylene and acrolein are the donors and oxygen is the accep-
tor.. The water reduces the work function only slightly and is also a donor
It was shown that the oxidation rate of propylene to acrolein and carbon

increasing copper concentration in the catalyst. 3) The activation energy
for the formation of CO2 on a copper - sillite catalyst was
26 - 30 kcal/mole, and on a copper - pumice catalyst, 23 - 25 kcal/mol'l.
4) The major part of CO2 was formed by oxidation of acrolein. Therefore,
the kinetics of acrolein oxidation was compared with that of propylene,
and the following was found: a) The oxidation rate is proportional to the
oxygen concentration and independent of the acrolein concentration; b) the
activation energy for the formation of CO 2 is 22 - 24 kcal/mole, and for
the formation of CO, 38 kcal/mole; c) the presence of propylene inhibits
the oxidation of acrolein. The authors intend to perform experiments
with tagged atoms to study this effect more thoroughly. The reaults will
be published in the next paper. There are 6 figures, 2 tables, and

same time and independently of one another several parallel
reactions take place, in which connection unstable intermediates of
the peroxide type are formed. Further some experiments were carried
out in which the effect of the contact time upon the oxidation
process of propylene was investigated (Fig 3). The acrolein yield
first increases on prolonged contact time but later remains constant
whereas the yield of carbon dioxide continuously increases. During
the oxidation of propylene on the copper catalyst the acrolein is
not completely destroyed. Probably at the saro time and
independently two reactions take place: The formation of acrolein
and its oxidation up to the carbon dioxide. The rate ratio of this
process is determined by the composition of the gas mixture. In
order to clarify the dependence of the aorolein yield on the
concentration of the catalyst an the carrier, several samples of
the catalyst on pumice and carborundum were investigated (Figs 4-7)-
'Ifie investigation indicated that the selectivity of the process can
be obtained by shortening of the contact time, by increase of the
linear velocity of current as well as by a decrease of the copper
concentration on the carrier which determines the course of the
process in the kinetic range. Under certain conditions the length

these processes are carried out in practice. A further develop-
ment of the investigation work under application of new experi-
mental methods will facilitate the production of oxidation ca-
talysts with certain properties within the near future. This
will render possible the carrying out of highly productive syn-
theses of monomers by means of the catalytic oxidation of hydro-
carbons. There are 6 figures, 8 tables, and 127 references, 72

dicals and can only be increased by the change of the chemical
composition of the surface of the catalyst. The taking place
of the catalytic oxidation is not only due to the selection of
an active catalyst but also to the fixation of optimum condi-
tions of the process. The formal kinetics of reaction is only
little investigated. The difficulties arising in connection
with the determination of kinetic rules are above all connected
with the exothermal character of these reactions which entails
an overheating of the catalysts and an intensification of the
parasitic processes. The data obtained by different authors
(Refs 9, 22, 56, 57, 61, 49, 120-124) which are in contradiction
indicate a complicated reaction mechanism (Table 7). Table 8
gives the values of the activation energy of various reactions
taking place during the oxidation of propylene. The field of
physical chemistry that deals with the investigation of the
effect of so-called macroscopic factors upon the rate of che-
mical processes and their kinetics is called macroscopic kine-
tics (macrokinetics). Figure 6 shous the investigation results
of the oxidation of naphthalene on melted vanadium pentoxide

and metals during the adsorption of oxygen; 5) mobility of GXY-
gen on the surface of the cataliat (Refs 64-97). The chemiso:,p-
tion of hydrocarbons on various materials has been investigated
by numerous research workers (Refs 56-58, 98-109, 116-119).
Table 5 gives experimeintal results concerning the variation of
the electric conductivity and the work function of vario-ja
metal oxides during the chemisorption of hydrocarbons. Table 6
shows the data on the activation energy and the adsorption
heat on various oxidation catalysts. The latter fact indicates
a differing mobility of oxygen on the surface of the catalyst.
In a homogeneous oxidation of hydrocarbons the peroxide radi-
cals are the active forms which cause the process. In the
course of the heterogeneous oxidation it is obviously the per-
oxide ion radicals that play the deAsive part. Oxygen contain-
ing compounds of the type of aldehydes, acids etc, which enter
coexistence together with the products of complete combustion
- carbonic acid gas and water - form in consequence of all
types of reaction of oxygen with hydrocarbon. The sflectivity
of the process is apparently due to the tight connection be-
Card 5/7 tween the bond and the surface of the forming peroxide iDn ra-

those of the exchange and the desorption of oxygen (Table 4).
The comparison of these data points to the fact that the con-
cepts concerning the redox mechanism of catalysis are invalid.
The inadequate development of the theory of catalytic oxida-
tion and the lacking of experimental data on individual stages
of the process have hitherto not permitted to set up a scheme
of the stepwise oxidation of hydrocarbons. The character of
the primary acts of catalytic oxidation is in close relation
to the nature of the active forms causing the process. During
the past years comprehensive material was collected concerning
the adsorption of oxygen and hydrocarbons on oxidation cata-
lysts. Of great importance for the mechanism of the oxidative
catalysis on metals and semicond,_-.c_tors are the adsorption of
oxygen and the character of its '~-_nd with t1- catalyst surface.
The results of several papers obtain-~d in norinection with the
investigation of chemical adsorption of oxygen on various solid
bodies may be divided into 5 ZrouPa: 1) Equilibri,-LT. and kine-
tics of adsorption; 2) heteroE;eneity of the surface; 3 dis-
solution of oxygen in the lattice of the solid body; 4~ trans-

foreign admixtures were the basis of concepts (Ref 16) concern-
ing the' impurities and admixtures as the main regulators of the
activity of the solid bodies and with respect to the chemical
character of surface activity. Essential for redox reactions
are the transitions of the electrons between the solid body and
the reacting molecules, Fig-ure I shows the dependence between
the velocity constant of oxidation and the amount of the intro-
duced admixture. The interaction between the solid body - the
catalyst - and the reacting medium often entails a variation of
the phase composition of the surface (Ref 16). Sometimes it. may
be the case that such a variation does not only occlar at the
surface but also inside. The chemical composition of the sur-
face of the catalyst exercises an effect, on both activity and
selectivity of the process. Isotopic exchange is one of the
methods permitting the determination of the mobility of the oxy~
gen atoms- or molecules at the surface and in the lattice. On
metal oxides the isotopic exchange proceeds much slower than
the catalytic oxidation reaction. According to the results ob-
tained by the author (Ref 42) the rates of the catalytic oxi-

obtained in the field of heterogeneous oxidative treatment of
hydrocarbons would have to be found as well as the factors
preventing these processes from developing towards the main
direction of organic synthesis. The investigation of the oxi-
dation processes indicates a division of these reactions into
solely heterogeneous and homogeneous ones, takini place,under
certain conditions. All oxidation processes have several im-
portant characteristic features of the reaction chemism in
common: the role of the peroxide compounds and of the atomic
oxygen, the propagai;ion of conjugate reactions,etc, as well as
the characteristics of the conditions of the process which are
in connection with the exothermal character of the oxidation
reactions. The most frequently used oxidation catalysts are
platinum, palladium, nickel, cc-rer and silver. Oxides of trans-
ition metals are used as oxidative semioonductor contacts
(Table 2). The earlier published survey (Ref 9) provided a com-
plete list of the oxidation catalyste, According to the modern

ABSTRACT: Catalytic oxidation is the most promising method of producing
monomers from natural gases and the gases occurring in the pro-
duction of petroleum. Until recently - as a result of the com-
plicated course of the process - it was not possible to obtain
any satisfactory results from theory as regards the practical
application of catalytical organic synthesis. In theory, almost
no use was made of the great practical experience in the se-
lection of catalysts. Roginskiy (Ref 1) divides the oxidation
reactions of hydrocarbons into 5 main classes. Table 1 gives an
incomplete list of the types of reaction of hydrocarbons with
oxygen. The types of process mentioned do not provide a com-
plete picture of the variety Of DOSsible reactions. Industry
has put into practice only part ;f these reactions. In principle
a further development of all mentioned directions would be pos-

catalytic hydrocarbon oxidation has hitherto turned difficult
the explanation of the mechanism of the different stages of
these reactions. The use of the most modern methods makes
possible the definition of the most important rules governing
this process. Some papers dealt with the investigation of the
chemisorption of hydrocarbons (Refs 3-4) which has to be
regarded as a condition for the further investigation of the
rules governing the catalytic hydrocarbon oxidation. The

Title : _02ld-es--of-TTdMition Metals as Catalysts of Oxidation of Hydrocarbons
Orig Pub : Zh. obahch. khimii, 1956, 26, No 5, 1368-1371
Abstract : Under dynamic conditions a strudy was made of catalytic oxidation of pro-
pyleae in mixtures of C H6 and 0 , of 1-1 composition, diluted with ai-
trogen, at ~00-4000. '2e stud,;g cataly'sts (C) are classified as follows:
1) C of extensive oxidation: Mn02, NiO, MgCr204, yielding,- 100% C02 and
H20; 2) C of destructive oxidation: V205-x-' 14003-x, W03-xf UO ... over which
are formed, in addition to C02 and H20, fo, Iddhyde, acetald4kyde, formic
and acetic acid; 3) C of selective oadation to acrolein -- Cu2O, which pro-
duced at 4000 a 60% yield of acrolein. It is assumed that active cata-
lysts of extensive oxidation are oxides with incomplete d-shells, while active
catalysts of mild oxidation can be catalysts of the type Ag and Cu20, in
which gaps in the d-shell arise on modification of these C by oxygen.
