The effect of the composition of hydrofluorio (HF) acid baths on, the hardening of silicate glass PERIODICAL: Steklo I keramika, no. 4, 1963, 13 15 TEXT: A detailed study was made of the effects of HF acid concentration, temperature, the presence of salts of fluorsilicio and other acids, on the hardening of silicate glass, with main emphasis placed on the study of the con-, centration of the HY acid. The purpose of the study was to clarify the nature of the glass hardening process in aeld baths, the chemical process taking place on them glass surface and the effect of the quality of the glass surface itself. Obtained experimental data coincide with thase of Lluzhavin who had found that the st-rength of glass depends on the concentration of the HF acid. It is con- eluded that the hardening of glass by proce&sing It in a 11F bath is accomplished not only Vj removing the defective surface layer; when studying the effect of Card 1/2 2/072/63/0()0/004/(Z4/005 The effect of the composition of... A051/A126 hardening, one has to consider the role played by the topoohemical processes 6n the glass-acid interface. At present, no direct proof is available on the structural change of the Slass.surface, but the rathor high Increase of the- strength of the silicate glass when processed in a 7.4 n solution of IF acid is attributed to it. It is recommended that this subject be studied in more detail including the effect of the pH and pF of acid baths on the degree of glass hardening. There are 3 figures.

The phosphor luminescence was excited by the filtered light of a PRK-4 mercury tube (365 mo). The Lumineacent light was incident, through a filter, on a photoolectronic multiplier bf the FEU-17 type connected with an amplifier. The following conclusions were drawn from the results of in- vestigationes 1. Determination of energies necessary for liberation of electrons from the deepest localization levels was performed Card 1/2 by 5 independent mothodes 4Q-13/48 TITLEt Investigation of Electron Localization Levels in ZnS u- Phosphor (Issledovaniye urovney lokalizataii elektronov v foafore ZnS-Cu) a. By analysis bf thermal do-luminescence curves, b. By analysis of regularities in the phosphor decay in the region of temperature quenching, and c. By analysis of the temperature-dependence of the light-sum in the region near temperature quenching. All three methods yield results agreeing well within the limits of m6asurement accuracy. 2. Within the tempForature range, in which the phosphor be- haves ideally, one can apply the method of decay analysis for the determination of the energy depth of these levels. The report was followed by a discussion. The bibliography lists 9 references, of which 7 are Slavic (Russian) INSTITUTION: Tomsk jtu;,e University. PRESENTED BYt By Vergunai F. I.

It can bo -,von from tablo 1 that not one of the trang-dihydroxo compounds (NH 3)2(0,1)4 Pt, (11H3OH )2(OH)2pt or (NH 3C')2 (OH )2pt react upon ammonia or sodium nitrite and do not exchange the hydroxy-group against bromine when potassium bromide acts on it. The hydroxy-group3, combined with highly trans-effective addenda, are variable. The process of neutralization of hydroxo-compounds is also connected with Card 1/2 the trans-effect.

The reaction of the two iso- mers on heating with concentrated ammonia or NaNO 2 was investi- gated to prove the fact found earlier that the OH groups are Card 1/3 passive on the axes OH-Pt.-OH and NH 3'- Pt-Off. No compounds with 68106 On the Geometrical Isomerism of Diamminotetrahydroxo- SOV/78-5 1-8/45 platinum.IV more than 2 ammino groups and no nitro compounds, respectively, were obtained even after a long treatment. In acid media, how- ever, the OH groups easily pass over into aquo groups which are considerably mobile and are easily replaced by Cl, Br, or NO 3 (Tables 6-8), the sequence of substitution depending on the po- sition of the group. The compounds Pt(NH 30HYNH3 Cl)Cl 2 and Pt(NH 30H)2C'2 weri obtained by treatment wizh HC1 (Table 9). The structure of these compounds was determined by reaction with HBr (Table 10). Since no dibromides but only the tribromide Pt(NH 3)2B3Cl anI the tetrabromide Pt(NH 3)2Br4were formed, the hydroxyl group is supposed to have a somewhat greater transeffect than the NH3 group.

ABSTRACT: Report describes the method employed in the synthesis ftnd separation of ethylsiloxnne polymers of linneir struct-ire with 3 to 5 Si atoma in the molecule. The catalytic regrouping method in the presonce of aluminum silicste was used in the derivation of ethylpolysiloxanes of linear structure. Hexnethylcyclotrisiloxane, octaetbylcyclotetresiloxAne and hexnathy2disilo-yane, were iised as the bnoic substances for the synthesis, The separntion of the individual polymorn from the hydrolysis products was accomplished by fractionation in a rectification tower with an effec- tiveness of 20 theoretical plates. During the fractionation of hexaethyl- disiloxnne, the rate of flow of the liquid was 200L..250 ml/hr and the reflux number was 10-15.

Fig. 2 shows the changi in viscosity of the compounds III and IV with the heating time at 2000C. Fig. I shows that the viscosity in the case of heating at 2500C grows more quickly with compound I than with compound II. The results obtained by the analysis of the chemical composition of the liquids investigated (Table) show that in the case of heating, the molecular weight and the silicon content in compounds with a methyl siloxane chain (I and III) increase more quickly than in compounds with the siloxane chain (II and IV which characterizes the destruction processes in the organic part of the molecule. The organomethyl silexanes (I and III) are also less resistant to thermooxidation. The substitution of the oxygen of the methylene group in the molecule chain of organosiloxane weakens the shielding effect of the siloxane bond in comparison to the silicon-organic frann groups, which leads to a decrease of thermooxidation stability of the frarm groups. The temperature coefficient of viscosity grows in the interval of from +50 to -30'C considerably in the case of substitution of oxygen in the siloxane Card 2/8 A99-L9 S/191/61/000/002/007/012 Com arative properties of oreano... :3124/3204 chain by the group -CH2-; in compound I it equals 330 and in compound II 35 (Fig. 3).

B101/B215 of catalysts on the cohydrolysis mixture of polymethyl-phenyl siloxanes has been studied, The action of H 2s0 4, KOH, FeCl,.6H 20, Al 2(so 4)3' 18H20, and natural aluminosilicate (treated with HC1) upon the products of co- hydrolysis of methyl-phenyl dichlorosilane and trimethyl chlorosilane (molar ratio of 5:2) has been examined. Cohydrolysis took place at 600C. The product was neutralized, and the content of Si and C 6H5 in the fraction 180-2900C was determined. Fig. 1 shows the change of viscosity under the action of catalysts; Table 1 gives the analysis of the products of cataly- tic transformation, The fact that viscosity at first increases rapidly when using KOH is explained by the intensive polymerization of cyclic com- pounds. No constant viscosity was attained for aluminosilicate, and the formation of benzene, i.e., separation of tne phenyl radical from siloxane, was observed, i,ith FeCl 3 and Al2(30 ),, the cyclic compounds were not completely rearranged at 200C, A temperature increase to 600C accelerated the reaction but then separation of phenyl radicals occurred.

Received 6/1M Reviewed 0/1957 ABbTRACT By several research works It was shown that the oxygen eliminated on the occasion of photo-synthesis originates from water. ~o far, how"~ver, no certain intermediate products of this reaction were proved. Although here hypotheses on the part of the carotenoids as oxigen-transporters were ex- pressed, a clear confirmation is still lacking. The authors applied a new method of inactivating the enzymes as well as chromatography on paper, and following the fluctuations of the relation of the 4 basic carotenoids, car- otene, lutein, violoxanthin and neoxanthin in leaves of several kinds of of plants. Lamellae were cut out from leaves of cyclamens, bakhalin-Duck- wheat, broad bean, dendelion and others and they were exposed to a 3H-8- lamp. The different intensity light was effected by di-rierent di3taces of the source of light. Lamellae which served for an experiment and as con- trol were fixed with acetone at -780. The analysis of the carotenoids was carried out according to the methodology previously described by the au- thors.

Tnis takes place in connection with an intense exposure to light. Illustration 2 illustrates the dependency of the fluctuation of tne aifference of tne content expressed as percen- tages of lutein and violoxanthin on the intensity or light. Already at 5,ooo 1k this difference increases noticeably and attains its maximum at d,ooo lk. Fiwther increase of the intensity of light has no influence on the difference. On the occasion of exposure to light of high intensity the sum of the content expressed as percentage of lutnein and violoxanthin remaint stable. Dimishing the intensity leads to the opposite effect. Tne phenomenon makes it possible to assume that in the green leaves tnere ex- ists a system of enzymes which regulates the proportion of lutein and violoxantnin. It is possible that tnis sj,3tem is related tothe oxygen transport in the process of photosyntnesis. (4 illustrations. 4 citations from blavic publications).

It is shown that the physicochemical properties of the pol ors Isolidifica- tion temperature, viscosity, activation energy of viscous flow, d4mg, n ZO) change somewhat with changing position of the benzene rings in the molecular Min. The viscosity of polymers with phonyl radicals on the sides increases more slowly during thermal oxidation than does that of polymers with benzene rings in the main chain (for the same number of benzene rings). This is due to the smaller number of the most readily oxidizable methyl radicals and to the screening effect of benzene rings T in the side groups. Me presence of benzene rings between the silicon atoms hinders the depolymerization of siloxano chains because of the difficulty of rupture and formation of low-molecular cyclic dissociation products.

The. test temperature was 200C (at this tempera- tur,2 the viscosity of 1, 11, and III was virtually the same). it was i fouad that for all three poly.,-.o-z.;, optimum lubricating properties are proauced by the introduct4-,i-. o.- four chlorine atoms per polyzer male- cu~.e' i.e., at a 16--7/. content. At this chlorine content, tae Poorast lubricating.Droperzies are -obtained~ ;inen all four 01 ato=s are concentrated in single phonyl"group; such a concentration clso con- siderably impairs thermal-oxidative stability. Polymers co~,taiining I or~_ 2 C1 atoms per phenyl group have virtually the same lubricating prop- CZLiCJ. Properties, test conditions, and test results are given for 1, 2/3
