Ko TITLE: Method of Determining the Pressure of the Saturated Vapor of Difficultly Volatile Substances PERIODICAL: Zavodekaya laboratoriya, 1959, Vol 25, Nr 9, PP 1097-1099 (USSR) ABSTRACT: A method van developed by which the sample is vaporized in an inert gas in a closed vesselp the inert gas acting as elastic medium which transfers the vapor pressure to a pres- sure gauge outside the high-temperature range. From the scheme of the gauge (Fig 2) it may be seen that the substance to bc investigated evaporates in a cylindrical quartz vessel which is housed in a furnace and is connected to a diaphragm zero- pressure gauge by means of a tube. The latter is contained in a thermostat and transmits the pressure to the pressure gauge which permits measurements with an accuracy of-* 0-5 torr. From the measurement results obtained on the apparati:a- deacrib- ad the pressure of the saturated vapor of KC1 was computed, and a curve of the dependence of the vapor pressure on tem- perature was plotted (Fig 3)- Comparison with the correspond- ing values in $tell's table shows good agreement of the data.

For this reason, the saturation vapor pressures of anhydrous LaCl 3' CeC13' PrCl,, and NdC1, were determined by an isothermal version of the "boiling-point method" (G. 1. Novikov, 0. G. Polyaohenok, Zh. neorgan. khimii, 6, 1951 (1961))$. It is suitable for measuring the vapor pressure of liquid and solid substances from 1 rim Hg to atmospheric pressure and above. Error is < + 0.1 mm Hg. The moment at which the vapor pressure above the substance becomes equal to the external pressure is established by fhe drop in the temperature of the substance when evaporation is intenaified near boiling point.

Novikov, 0. G. Polyachenok, Zh. neorgan. khimil, 6, 1951 (1961)) In the.resulting diagrams (log Ptotal; 'OOO/T, OK) the lines of the total saturation vapor pressure for melts of different composi'tions lie between those of the pure compon ents KC1 and LnCl 3* Their order agrees with the changes in concentration of the melts.

B106/B180 LnCl3salts to mixtures containing ever more KCI. This may be due to dissociation of the compounds in the melt as the temperature rises. The systems studied deviate considerably from ideal mixtures, in a way which indicates considerable association in the salt melts. With the analytical method used chemical analysis of the condensates is possible. The sum of the analytically determined elements was in good agreement 'with the results of direct weighing of the condensates. Comparison of the vapor compositions with the corresponding compositions of melts showed that the vapor contained far more LnCl3 than could be expected if only KCI and LnCl are mutually soluble without the formation of double salts or their evaporation on heating. Plots of vapor versus melt composition show that some form of the double salts between KC1 and LnCI3must be volatile, The rare earth content of the vapor decreases with rising temperaturef which may be due to dissociation of the volatile forms of the oompounds in the melt.

The rectifier substation was set up at the 6 kv sub- station supplying the Vtuzgorodok (Institute area). For installing the inventors, free chambers in a sub- station feeding one of the training buildings were usedl of which a part was occupied by UEA. The recti- fied voltage was 12 kv. The equipment of the recti- fier and inverter stations was designed for transmit- Card 2/5 ting 180 kw. The length of the overground line was SOV/143-58-10-18/24 The Experimental D.C. Power Line from UPI to UEA somewhat shorter than 500 m. In a special laboratory preliminary studies were conducted with the rectifier and inverter equipment, emphasizing safety measures, since a number of students did not yet have the re-- quired experience. The equipment was installed upon completion of the construction work by a group of 12- 15 senior students. The experimental operation was also performed by students, among them B.A. Astakhov, P.N. Zakharov and his brother, Kokin, Teploukhov and others. The Ekspluatatsionno-tekhnicheskoye upravle- niye UPI (Operational-Technological Administration of UPI), S.A. Yakimov, N.A. Morozov, M.A. Bobich and others, furnished great assistance for this project. The first period of operation of the d.c. power line was characterized by short duration of stable power transmission. After two to four hours various mal- functions of the six-anode mercury rectifiers occur- red, etc. Some research work was conducted on a contract basis with the "Uralelektroapparat" plant Card 3/5 and the Institut postoyannogo toks, MES SSSR (Institute SOV/143-58-10-18/24 The Experimental D.C.

The method described by Xurtenaker (Zo Inorg. Chem., 142, 115, 1925) served as its basis. The sample is heated in a 0,5 n sodium sulfite solution. Then the solution is increased to a certain volume with zinc acetate and investigated again. It is then titrated with a 0,05 n iodine solution. The duration of the analysis is 20 - 30 minutes. The method may be used for the determination of the poly- sulfide sulfur and free sulfur in the presence of greater quantities of thiosulfate (up to 70%) and thiocyanate Card 1/2 (up to 30G/'.).

In the pre- sent article the authors describe a method ofquantitatively calculating and ex- perimentally determining the inhomogeneity content by measuringthe gradient of the resistivity and the lifetime of the excess carriers. The formulas for the quantitative calculations are derived brieflyl using the theory of V. Yes Lashkarey and V. A. Romanov (Tr. Inst, fiz.,UkrSSR v# 70 501, 1956t and J, Tsucj Czeeboal. Jour. Physe v* 50 1789 1955). The experimental setup to show in Fig. I of the Cord. 1A L U17 -66 ACCESSION NR: AP5022690. Enclosure. measuremcnts were made on n-Ge single crystals grown by.the Czochralski method with impurity concentration 2,2 x lo13 cm-3. When the investi_~ gated sample Is illuminated by the traveling light spot, the oscillographic curves. give the distribution of the inhomogeneities over the entire volume of the crystals simultaneously. The volume-gradient photo-emf curves give the distribution of the'. electrically active impurities, while the photoconductivity curves yield the lifetimes of the minority carriers. The resistivity.gradiznt is determined from :the amplitudes of the photoconductivity and volume-gradient photo-emf curves. The dependence of the lifetime on the concentration of the'electrically active im-o' purities is determined from the character of the photo emf distribution curves. The experimental results show that.theory does not take into account some'of the, factors such as the internal fields produced when the electrically active impuri-~~ ties are unevenly distributed, and must therefore be treated with cautione The i~ results show also that even when the electrically active impurities have a highly~ uneven concentration, the minority carrier lifetime may still be constants An advantage of the method Is higher sensitivity and shorter measurement time as com- pared with methods based on the measurements of the conductivity along th-t Icrystal.

The n-InSb diodes were made of thin slabs cut from single crystals with 1013 to 1.2 x 1015 cffr3 concentrations from 7.8 x . All measuremerts;-'- were made at liquid-nitrogen temperature# but self-oscillation was observed also at higher temperatures. All diodes exhibited on the reverse branch of the current-voltage characteristic two regions of Card 1/2 16125-65 ACCESSION NR:..,AP5000696 negative resistance, where the oscillations occurred. Some diodes -had negative-resistance regions on the forward branch, too, but the oscillations were more difficult to excite there. The oscillation effect varied with the inverse current and the frequency, and also was sensitive to application of an external magnetic field. Typicall oscillograms are shown and some of the peculiarities of the pheno- menon are described. The author ascribes the negative-resistance branenes to the formation of definite states on the surface of the crystal. "The author thanks Ye. G.

Oscillations were observed when bias was applied across sample p-PbS point-contact diodes. The specific resistivity of the p-PbS crystal3 was reduced to 0.07-0.01 ohm/cm, by heating the crystals for several hours at a temperature of 400C in a cerium vapor medium.. The crystals were I then oxidized in air at a temperature of 500C. Point-contact diodes prepared in such a manner had forward resistances from 200 to 1000 ohm and reverse resistances from 0.01 to 0.3 Mohm. Oscillations at fre- quencies of 77, 62.5, and 57.5 kc with maximum amplitudes of 0.5, 0.37, and 0.22 V respectively, were observed across the prepared samples. The oscillations occurred at reverse bias voltages from 18 to 29 v and re- verse currents from 200 to 800 Vamp. Oscillation at a frequency of 300 ke with an amplitude of 0.3 v was observed across a sample with a uDc: 621.

TITLE: Synthesis of IP4-Diisopropylbenzene -an-T-N-me of its Conversions (Sintez 1#4-diizopropilbenzola i nekotoryye yego prevrashcheniya) PERIODICAL: Zhurnal Obshchey Xhimii, 19589 Vol.~ 28l Nr 5, pp.-, 1279 - 1264 (USSR) ABSTRACT: In the present work the alkylation of the isopropylbenzene with propylene in the presence of BP 3' H3PO4 was dealt with. When using these three compounds at equimolar ratios (4 : 1 : o,26) at 98 - 1000C the 194-diisopropylbenzene was obtained in a yield of 73% (at 52 to 550C - 19%). The oxidation of the 1,4-diisopropylbenzene (in liquid phase) with atmos;bwic oxygen in the presence of various stimulators in mono- and dihydrogen peroxide was investigated. During some time of this oxidation an accumulation of peroxide to a certain maximum takes place, on which the decomposition begins and the amount Card 1/3 decreases. At 11o0C such a maximum is reached after 12-14 hours, 79-28-5-37/69 Synthesis of 1,4-Diisopropylbenzons and Some of its Conversions at 650C after 20-4o hours, depending on the otimulators. The stimulator mixturep consisting of manganese resinate and cobalt acetate with an addition of calcium hydrogen peroxide stimulates oxidation much more than the first two, taken singly. The addition of sodium ste~Zarate to the mixture accelerates the oxidation and makes it possible to obtain 51% hydrogen- peroxide at 850C during 17 hours, whereas without stesrate only 33% result at 11o C during 16 hours, on which the decom- position of the peroxide litarts. Calcium-hydrogen-peroxide also accelerates the oxidation and strengthens the hydrogenperoxide which leads to a deeper oxidation. The oxidation is mainly directed to the formation of monohydrogen peroxide of the diisopropylbenzene in the cleavage of which in acidous medium the 4-isopropylphenol forms in a yield of go%. Partially also dihydrogen peroxide of the diisopropylbenzene forms which Card 2/3 then splits into hydroquinone.

Thereby the structure of the large entrprises was determined by the technology of the synthesis of isopropylbenzene from benzene and propylene in the presence of aluminum-chloride as catalyst. This first of all guaranteed the common industrial production of phenol and acetone (reference 1), An earlier paper reported that the oxidation of alkylbenzenes in the liquid phase whicb were pro- duced by thealkylation of benzene by means of olefins in the pre- sence of boron fluoride (reference 2) is also studied (reference 3). The oxidation in the liquid phase takes place according to the equationst (CH,),CH
