PERIODICAL: Doklady AN SSSRy 1957, Vol. 116, Nr 4, pp. 641-644 (USSR) ABSTRACT: The xanthine dyes eosine, erythrosine and bengal pink are frequently utilized photosensitizer of oxydation and polymerization processes. A potentiometer method was employed for studying the photo reduction and photo oxydation of xanthine dyes. In the present paper the measurements of the photo galvanic effect permitted the recording of the formation of the intermediate products in the redox- reactions of some dyes. The experiments were conducted in a container with platinum electrodes. The authors established the following facts in complete accordance with the results obtained from chlorophyll theophitine (feofitin) and other pigments. The illumination of an alcoholic solution or of a pyridine solution of a xanthine dye ( C = 10-6 -10-3 ,01/1) shifts the electrode Card 1/3 potential towards the positive in the presence of oxygen. Note on the Intermediate Products in Rodox Photoreactions 20-4-31/51 of Xanthine Dyes An illumination in the presence of reducing substances (alcohol, pyridine, ascorbinic acid, aldehyde) shifts the electrode potential towards the negative. A diagram illustrates the kinetic curves of the modification of potential of a platinum electrode, which is immersed in a pyridine solution of eosine. The measurements were conducted with different light intensities from I = 1 to I = 0,08. On illumination the potential decreases, reaches a certain minimum, the increases again and returns to the original value. The modification of the photo potential observed here is connected with the existence of an intermediate product. The condiderations institute by the authors also explain the dependence of the kinetics of the modification of the potential on the concentration of the dye, which has been observed experimentally. An increase of concentration of eosine shows in Ueneral the same influence on the kinetics of the process as an increase of the light intensity. On a cooling down the velocity of the potential reversal decreases quickly. The character of the dependence of the Card 2/3 kinetics of the modification of the potential on temperature Hote on the Intermediate Products in Redox Photoreactions 20-4-31/51 -of Xanthine Dyes distinctly speaks in favour for a stage-like character of the reduction process. Finally, a few words are said concerning this reaction at various pigments. There are 4 figures, and 3 Slavic references. PRESENTED: April12, 1957, by A. N.

The data of the thermodynami'c properties of air at several 1 OOOOC are to be found in the papers by Davies (reference 1)V M. P. Vukaiovuch (i-eference 2), Ya. B. Zelsdovich and A. I. Polya-.nyy (reference 13), as well as Llyr-is and Ellbe (reference 4)9 whereas the present work performs determinatlons of the thermodynamic properties of air at temperatures where the dissociation-is finished and Card 113 where only ionization and radiation take place. The The Thermodynamic Properties of Air in Thermal 76-32-3-27/43 Ionization and the Shock Wave investigations were not made in natural air, but in a mixture of 79.1% nitrogen and 20.9% oxygen (by volume). In the calculation of the statistical sums, it is emphasized that the number of energy levels shall be limited, for the solution of this problem is considered complicated and the selection of the number of levels is practically arbitrary. In the present work the number 10 was never surpassed. It is said that a wrong selection of numbers exerts little influence upon the final results. The obtained experimental results show that at temperatures of 200,000 - 400,000 OC the gas mixture mainly consists of free electrons and nuclei of nitrogen and oxygen with 2 helium electrons, this being explained by the higher dissociation energy of the two last-mentioned electrons. The results of the calculation of the thermodynamic quantities are given in tables. From the obtained results and diagrams follows that a great influence of the dissociation and ionization upon the Card 2/3 front parameters of the shock wave is exists, the latter propagating The Thermodynamic Properties of Air in Thermal Ionization and the Shock Wave with velocities up to 115 km/sec.

TITLE- Mechanism of the Photoreduction of Xa.,it',!--"e D~,estuffs (l,',ekhanizm reaktsii fotovosstanovleniya ks-=tenovykh krasiteley) PEdIODICAL: Izvestiya kkademii nauk SSSR. Otdeleniye khimicheskikh nauk, 1959, Nr 4, pp 637-643 (USSR) ABSTRACT: The photoreduction of xanthene dyestuffs consists in a trans- formation of the dyestuff into a colorless leuco -~;,;mpound; the dyestuff is completely bleached out when the reaction is completed. Eosine, erythrosine, chemically pure Bengal pink and ("ch.d.a")ascorbic acid were used in the present work whereas ethanol and pyridine were used as solvents. A typical kinetic curve of the potential change of the platinum electrode dipped in the dyestuff solution exposed to light is shown in figure 1, It is seen that the potential changes quickly in the negative direction upon exposure to light to reach the minimum and return to the initial value. This course has been ascribed to the presence of an intermediate product formed during the reduction of the eosine. With the aid of potentiometric measurements it Card 1/3 has been found that the intermediate products formed during the Mechanism of the Photoreduction of Xanthene Dyestuffs SOV/62-59-4-10/42 reduction of the dyestuffs are sufficiently stable and have a life of -300 to -400 minutes. In view of the data found on the life and on the conditions under which the highest concentra- tions of intermediate products can be obtained the photoreduc- tion of the xanthene dyestuffs has been subjected to spectral analysis. The spectra of the intermediate products are shown in figure 3. As the spectrum of an intermediate product depends neither on the dyestuff nor on the reducing agent this compound can be assumed not to form any complex with the dyestuff or the reducing agent. Figure 4 shows the kinetic curves of the inter- mediate products of eosine and the potential change of the elec- trode determined during an experiment conducted at room tempera- ture. These data indicate that the concentration of the inter- mediate product at the time when the light is removed is cEff>7 10- 6 or 20% of the initial concentration of the ,_ - 11 - eosine. The highest concentration reaches 354,. Based on the same data the molar absorption coefficient of the intermediate prod- uct has been obtained (E EN)427 1.1 . 104 1/mole-cm. As is ap- Card 2/3 parent from figure 5 the highest optical density of the inter- Mechanism of the Photoreduction of Xanthene Dyestuffs sov/62-59-4-10/42 mediate product at -350 reaches 0.62, which means that it is about five times higher than at room temperature. The estizia- tion of the maximum concentration in view of the amount of dye- stuff regenerated after the removal of light has led to the values c... ~/>42% of4the initial eosine and (E EN) 427,,:~,4-4 - 10 1/mole-cm. The cause for the great varia- tion of the EEN values with temperature has not been clarified. It becomes evident from figure 6 that the potential reaches the zero level more quickly at a higher concentration of the reduc- ing agent. This shows that the intermediate product is consumed more quickly than it is formed. There are 7 figures and 5 ref- erences, 2 of which are Soviet.

Seriya fizicheakaya, 1959, Vol 23, Nr 10, pp 1265 - 1266 (TJSSR) kEBSTIUCT: The present paper intends to explain the nature of the inter- mediate products in the photochemical reactions of eosin and.. chlorophyll. The investigations were carried out at room temperature with high-frequency modulation of the magnetic field. Method and apparatus are described in references 1 and 2. First, some results concerning the photoreduction of eosin are discussed. This reaction consists in the transforma- tion of the dye into a leuco-compound and has already been potentiometrically and spectroscopically investigated (Refs 30). The authors assuined that a comparatively stable intermediate product is formea (semiquinone dye), Aich may have a life of several seconds at room temperature.

The photochemical reaction which de- velops by way of a biradical, is shown schematically and has already been described by Schenck (Ref 5). The authors of the present paper were the first to investigate the resonance spectrum of a live leaf. A leaf of agrophyrum repens was used for this purpose. The resonance signal showed a doublet, hyper- fine splitting amounted to AH = 1.8 + 0.2 Gs. There are 5 ref- erences, 4 of which are Soviet.

Next, an expression is written down fo*he rate of the reaction for this scheme for the case of long chains, and is then specialized for the case of sufficiently hi.'rh concentrations V-021 of oxygen: d ~02] 1/2 ./2 [RHJ . In the case of short chains - = w k k dt 1 3 6 the initiation rate w i must be added to the right Dart. The last-mentioned equation contains 3 unknown quantities wi9 k3 and k6, and accordingly~ three independent relations are required for the separate determination of these three quan- tities. The theory of the method of continuous illumination of such a decomposition has already been discussed in an earlier paper (Ref 3). By means of this method it is possible to measure the mean life of this chain, or, which is ihe Card 2/4 same thing, the mean life T of the radical. Formulas for the SOV/20-124-4-43/67 The Determination of the Elementary Constants of the Reaction of the Oxidation of Ethyl-benzene by the Method of Intermittent illumination determination of T are written down. Carrying out of the experiments is described in short. The rate of reaction is determined from the absorption of oxygen in a vacuum device with automatic recording. The light source used was a mercury lamp SVDSh-250. which was fed with direct current. The next chapter-deals with the determination of the initiation rate. The experimentally determined dependence of d 10 21 /dt on the concentration i/[Bj of the inhibitor,is shown by a dia- gram. The straight lines for 4' inhibitors at different tem- peratures intersect at one and the same point, which is indicative of the fact that the additions of these inhibitors do not modify the initiation rate itself and that the latter also does not depend on temperature. This fact was used for the direct measurement of the quaritity w.. For this purpose the dependence of the reaction rate on temperature was deter- mined. In the case of sufficiently low temperatures (5-15') the reaction rate does not depend on temperature. Within this temperature rIn e the length of the chain is near zero, and it holds that df021 /dt = w'. The values of w. determined Card 3/4 by the inhibitor method ani from the temperaiure-dependencG SOV/2o-124-4-43/67 The Determination of the Elementary Constants of the Reaction of the Oxidation of Ethyl-benzene by the Method of Intermittent Illumination of the reaction rate are in practical agreement. Furthermore, the initiation rate was determined by means of the second method, because more accurate results may be obtained in this way within a shorter time. In the last part of this paper the life-times of peroxide radicals are determined. There are 4 figures, 1 table, and 6 references, 1 of which is Soviet.

Isodecane (2.7-dimethyl-octane) was used as test object. Preliminary tests shcwed that if ozone is blown past during a short time the reaction is accelerated considerably. The authors recorde& a weak glow which was produced during the bubbling of oxygen (containing 2-3 % ozone) by isodecane. This isodecane was in a glass cxidatlion cell at temperatures of 20-900. By glow the photomultiplier FEUz-19 served as an Card 1/3 indicator of the glow.

The luminescence in question occurs with the decomposition of some or.-anic compounds in hydrocarbons as solvents. A figure illustrates the scheme of the apparatus used for recording the luminescence. The reaction takes place in a cuvette placed in a transparent chamber. The cuvette is enclosed by a water-heated outer glass wall which acts as a thermostat. The image of the clavette is then projected onto the photocathode of the ohotomultiplier FEU-199 and the current supplied bj the latter is recorded by an electronic potentiometer EPPV-51c The authors investigated the thermal decomposition of the hydrogen peroxides of Tetralin; 2.7-dimethyloctane; isopropylbenzene; benzoyl Card 1/3 peroxide and isoazobutyronitryl.

Otdeleniye khimicheskikh nauk, 1960, No. 8, pp. 1337-1341 TEXT: The present publication treats a phenomenon observed during the nickel-distearate catalyzed oxidation of various hydrocarbons. The authors observed that in these reactions the maximum concentration of the hydro- peroxide fairly eQuals its concentration in an uncatalyzed reaction. It was shown that the anomalous course of the kinetic curve of the hydro- peroxide during the oxidation of ethyl benzene is connected with an in activation of the catalyst. Various experiments were cade to establish the cause of the reduced activity of the catalyst during the oxidation process (Figs. 3, 4). These experiments lead the authors to assume that products reacting with the catalyst and reducing its activity are formed during Card 1/3 86408 On the Change in Catalytic Activity of Nickel 3/062/60/000/008/015/033/XX Stearate During the Oxidation of Ethyl BenzeneBO13/BO55 the reaction. Since acids accumulate during the oxidation of the decompo- sition products of hydroperoxide, it seems likely that these very acids inactivate the catalyst, e.g. by forming insoluble salts (Refs. 2-4). Ex- periments performed in this direction showed that tile reduced activity of the catalyst is indeed related to its reaction with these acids (Fig. 5). Theestablished reduction of catalyst activity during the reaction permits a simple explanation for the accumulation of peroxides during the nickel-stearate catalyzed reaction (Pigs. 1, 2). Till the maximum peroxide concentration is reached, the nickel salt is completely inactivated. The reaction is then practically uncatalyzed and the maximum peroxide concen- trations are therefore in agreement. At the same time the maximum concen- tration is reached more quickly in the presence of nickel stearate since the latter has a strong catalytic effect at the outset of the reaction. The results of this investigation furnish further proof that in the cata- lytic oxidation of hydrocarbons metal salts are no catalysts but rather initiators of the process. Their activity, and frequently also the mechanism of their effect, change during the process. The observed reaction kinetics therefore reflect not only the properties of the reacting system, but also the changes in the activity and action of the catalyst in the Card 2/3 On the Change in Catalytic Activity of Nickel ~"/6t/UOO/O0'8/015/O33/XX Stearate During the Oxidation of Ethyl B013/BO55 Benzene individual stages of the reaction. In studies of the catalytic mechanism, stabilization of the catalyst is particularly important.

TITLED Catalytic decomposition of ethyl benzene hydroperoxide PERIODICALt Akademiya nauk SSSR. Izvestiya. Otdeleniye khimicheskikh nauk, no, ~?,. 1,961, 788 - 796 TEM The systems consisting of a metal salt of variable valence and a peroxide are frequently used as catalysts in the oxidation of hydrocar- bong and as initiators in the radical polymerization, The mode of action of such systems is based on the fact that they produce free radicals and L . -- ,hus -increase the ~n-i"ation rate of the chains, The salt catalysts under- go a change during the ~xidatiori process in the oxidation of hydrocarbons. During the reaction the valence of 'he metal changes, and complexes are formed from the metal salt and the reaction products with the metal salt being preripitated in certain cases. The catalyst may play a part not only 1-n the in.Lriation of the chains, but also in the chain rupture and, apparen7 Ij in the 9P--)ngation of the chains. Such changes of the catalyst and i's manifold functions highly complicate the reaction kinetics and Card 23587 0 S/062/61/000/005/002/009 Catalytic decomposi~icn of- B118/B208 make it difficiilt to under3tand ~he mechanism of the catalytic effect of metal salts. In order to solve this general problem the authors analyzed the reaction of the catalytic oxidation of hydrocarbons, and studied each single 3tage In the present paper one of the most important reaction stages of the catalytic reaction is studied, i., P., the reaction of a hydroperoxide with a me-al salt whose metal has a variable valence. The k-,nE,tjcs of thQ catalytic decomposition of ethyl benzene hydroperoxide was inv:?stagated. The initial dpccmposition rate is proportional to the con- centration of the -:catalyst (of copper stearate anQ hydroperoxide). At a high hydroperoxide excess, rhe catalyst is converted to the inactive form cf monovalent copper during the reaction, which is stopped. The amount of decomposed hydroperoxi-de increases with increasing concentration of the catalyst and of hydroperoxide, as well as with rising temperature. Decom- position mainly proceeds accord-Ing to the catalytic mechanism; the chain mechan:sm is of minor importance. When 'the reaction was carried out in the presence of an inhibitor (diphenyl picryl hydrazyl) it was found that the rate constant of the inhibitor consumption considerably exceeds that of the catalytic decomposition of the hydroperoxide.

TITLE: The possibility of using the method of electron paramagnetic resonance to record the active centers in the oxidation of hydrocarbons in the liquid phase PERIODICAL: Akademiya nauk SSSR. Doklady, v. 139, no. 6, 1961, 1409-1412 TEXT: The authors studied the applicability of electron paramagnetic resonance (epr): a) for determining free radicals; b) for measuring the steady concentration of these radicals in the oxidation of hydrocarbons. A continuation of these studies will probably contribute to the knowledge of the kinetics of processes of other types. From the measured values it is possible to determine directly the rate constants of the elementary reactions that constitute parts of the entire process. Since the concentration of the radicals is low, their determination under steady conditions is difficult. For this reason the active radicals could not be identified during the oxidation of hydrocarbons in the liquid phase. 2 types of active centers take part in the oxidation of hydrocarbons: Card 1/5 2865 S/020'N1/139/006/021/022 The possibility of using the itethod ...

It is approximately equal for the following substances: cyclohexene, methyl cyclohexene, 1-octene, dihydromyrcene, ethyl linoleate, digeranyl, tetralin, ethyl benzene, cumene, n-decanal, and benzaldehyde. Under w d(RO w 2 steady condition.. dt 0, and (R02) = F-ki, (1). Hence, the steady 6 concentration of the R62, at a given initiation rate, is the higher the lower the rate constant of R62 recombination. An increase of the constant to the threefold increases the steady concentration only to the 1-7-fold. In aromatic hydrocarbons, tetralin and ethyl benzene, in which the peroxide group is located at a secondary hydrocarbon atom, the recombination constant is by 1-2 orders of magnitude higher. Among the substances mentioned the cumyl peroxide radicals recombine with the smallest constant. In order to prove the existence of the peroxide radicals their concentration must amount to at least 1-1015 to 5*1015 radicals/CM3.

The folloving substances were used for the oxidation: T) azoblel4sobutyronitrile, II) dicyalohexyl peroarbonate, III) cobalt stearatq, and IV) cobalt acetate. Different initiators give identical spectra. The spectrum is a wide, almost symmetrical singlet (&H~_,18 +2 oersteds) with a g factor of 2.015 tO.001. According to the Shi+'z of the g factor and the effective line width, this spectrum is similar to the epr spectrum of the peroxide radicals in the solid phase. in control tests in which isopropyl benzene was replaced by ethyl benzene no epr spectrum was observed in any of the initiators mentioned. Besides, epr absorption disappeared when the oxygen supply was stopped and when .'rogen was blown through for a short period.

In experiments with II) the authors measured concentra- tions of 4-1015 to 2*10 16 radicals/CM3. The rate constant of decay of 10 into radicals is unknown. The authors assume that its decay rate is equai tc the decay rate into radicals. Thus, they calculate the initiation rate and find that the measured concentrations of the RO2 radicals are 114 to 4,'12 of the calculated values.

The variations in chemiluminescence and pressure vere recorded automatically; vhen indicated, the end products were sub.jected to chemical analysis. The time variation of the chemlluminescence incident to oxidation of acetaldebyde proved to be distinctive; most curves exhibit two peaks; one sharp, the crther flat (the time curves and spectra for oxidation of acetaldehyde are reproduced). This -; icates that the reaction ind proceeds in two stages. Hence observation.of chemiluminescence provides a means for stiidying the kinetics of some chemical reactions. Orig. art. has: 3 figures.

TITLE: Formation of excited formaldehyde molecules in low-temperature oxidation of acetald-ehyde Pj~'RTODICAL: Akademiya nauk SSSR Doklady', v. 148, no. 2, 1963, 388-390 TEXT: The project consisted in determining the chemical nature of I he_. luminescent particles in the oxidation of acetaldehyde. It is pro4khat in this reaction the luminescence is connected with the formation of 6x- cited formaldehyde molecules. Chemi-luminescence in reactions which pro- ceed under formation of alkoxy radicals is ' also explained in this way. The luminescent particles in the slow oxidation of acetaldehyde in the gas phase are identified experimentally by taking the chemi-luminescence spectra With a high-power spectrometer developed by R. F. Vasillyev, S. It. Petukhov and T. N. Zhuchkova; the instrument is described in ZhvKh, V- 36, No. 10, 2284 (1962). The chemi-luminescence spectrum of a mixture of 50 mm. Hg acetalde-. hyde and 47 mm Hg oxygen was taken at 1820C, chemi-luminescence having a maximum valuz. The kinetic c4*rve of chemi-luminescence has two peaks. I n Card 1/-1 --/020/63/148/002/037/037 Formation of excited formaldehyde ... B124/-B186 the section following the necond peak the intensity of luminescence changes but little with time. Tt has,been found that the Spectrum taken in this section practically coincide 's with the fluorescence spectrum of formalde- hyde. The formation of formaldehyde in the reaction products is proved also by chemical analysis. With the aid of,light filters it was shown that between 180 and 1200C the oosi,tion of the luminescence maximum and the total shape of the spectrum do not change. Hence it can be concluded that also at temperatures below 1800C th 'e second luminescence maximum is related t*o the formation of formaldehyde. The kinetic curves of 1 ,uminescence at 1820C and with a composition of the mixture of 50 mm Hg CH3 CHO and 35 mm H9 02 were taken at 370, 425, and 510 mi;. It.was found that the intensity ratio remains practically constant. This prov'es that also in the region of the first DC-ak, luminescence is connected with excited.formaldehyde molecules. This example shows that the reactions necessary for the formation of excited formaldehyde molecules take place not only in cool flames but even at much lower temperatures. There are 3 figures.

The chemiluminescence in thisteaction- depends on the recombination of peradde-radicals formed as a result of the' catalyzed decomposition of hydropervxide~ The intensity of chemiluminescence is proportional to the speed of decomposition. 7he value obtained from the light intensity curves and from the analysis of hydroperoxide decomposition are in agree- ment. This gives a possibility of utilization of.chemiluninescence methodfor the investigation of the kinetics of catelyzed.hydroperoxide decomposition. -it Vw found that the higher the concentration of catalyst, the higher is the maxEm= intensity of the chemiluminescence.

Cu- myl peroxide was selected for further study since it has the smallest recorabina-'. tion rate constant. The oxidation of cumene was then effected in the resonator Card 1/2 ACCESSION NR: AP4016517 of the EFR spectrometer. The reaction was catalyzed with cobalt stearate or initiated with azobisisobutyronit rile or-with dicylohexylpercarbonate. In chang- ing the concentration of the latter from 0. 02-0. 55 mol. /1. , at 68-50C, the ini- tiation rate changed by a factor of 50, from 5x !or-6to 2-4x1o-4mo2/1_rec. The EPR:.' spectra, determined by the cumyl per-oxide radicals,are identical, although oxidation was initiated by different radicals. The peroxide radical concentration;~ measured in this work essentially approaches the values calculated from the I known rate of initiation and the recombination rate constant. The slightly lower measured values are explained as due to experimental errors such as insuffici- ent 02, incorrect placement of the ampoule in the resonator, etc. Orig. art. has: 2 figures, 4 equations, 1 formula ASSOCIATION: Institut khimicheskoy.fiziki AN SSSR (Institute of ChemicRI Physics AN SSSR) SUBMITTED: 26Apr62 DATE ACQ: 1OMar64 ENCL: 00 SUB CODE: CH, PH NO REF SOV: 007 OTHER: 013 Card 2/2 KOZLOVA, Z.G.- TSEPA T I LOV9 V.F.; SHLYAPINTOKHS V.Ya. -~.- - - .. -,-- ..
