The crystals%'ere'g5ro from anhydrous cadmium fluoride pro- duced by sirtering a mixture of cadmium oxide with ammonium fluoride. The hydrogen fluoride released during thermal decomposition converts the cadmium oxide into cad- mium fluoride. Litmus paper may be used for determining the-degree of conversion. The vapors released during the,process are alkaline, changing to neutral or weakly Card 1/2 UDC: 535.37 : 548.0 L 15562-66 ACC NR: AP6004410 acid at the end. This indicates decomposition of excess ammonium fluoride. The purity of the initial reagents has a strong effect on the quality of the product. Absorption spectra were used for checking the degree of purity of the final crystal. Crystals were produced with a transmission factor of 30% for a thickness of approxi- mately 5 mm at a wave length of 200 mp. Activator concentrations were 0.2, 1, 5 and 10 mol.% for CdF2 crystals with NdF3 and 0.2 mol.% for crystals with the other lan- thanides. The following trivalent activating ions were studied: Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tu and Yb. A comparison of the luminescence spectra for ihes 'e ions in cadmium fluoride and calcium fluoride crystals shows that in spite of the identical types of lattice and the close parameters, the behavior of rare earth ions in these crystals has very little in'common. This is emphasized particularly in the luminescence spectra for trivalent Pr, Dy and Tb and in the absence of luminescence for thulium. The difference between these two matrices shows up in the valence of the impurity ions. For instance europium is usually bivalent in calcium.fluoride, while it is always trivalent In cadmium fluoride. This may be explained by the dif- ference in oxidation potentials for bivalent calcium and cadmium. Orig. art. has: 6 figures.

From two experimental series we may conclude that in the caoc of the application - of 25~a Na.011-solution as dehydrochlorinating reagent a product is obtained which approaches most closely the methyl ester of the a-chloro acrylic acid. This ester is an achromatio~ liquid with characteristic lachrimatory properties. It causes burns of the skin. Then the prodi,ction of the mentioned ester from a-chloro acrylic acid and trichloro ethylene is described. The dependence of the yield in eaters with regard to time was determined for an experiment with the following quantity of reactinCe substances: trichloro ethylene 100.0 g (0.763 mole), formalin (of A~o) 76.3 G (0.763 mole), sul- phuric acid 316.0 g (3.230 mole), methyl alcohol 30.6 & ZO-957 mole), and copper carbonate (as inhibitor of the poly- merization) 1.3 g (Fig 1). This shows that the maximum yield (N2' of the theory) of the methyl ester of a-chloro acrylic acid is obtained within 3 hours. The yield is reduced in the case of a further heating of the reaction mass. The dependence of the ester yield on the H 2so 4 quantity is shown in table 2.

When carrying out the interaction reaction of benzene with diols the authors relied on data from pre- ' vious investigations (Refs I to 8).

It has been ascertained that the interaction o? binzene witA butane-diol-1 A leads to the formatVion of tarry products and with butane-diol-1,3 to 3-phenyl- .,butanol-1 and 1.,3-diphenylbutane. The dehydration was a separate problem,~as it is known from publications (Refs 9 and 19) that the extension of the radical of the respective alcohol makes its dehydration more difficult. The dehydration was carried out under the conditions su.-gested for the primary phenylethyl alcohol'(Refs 9, 11, 12). The highest yield of 2-phenyl-butene-3 (56 %) is ob- 0 tained in the presence of alumo-silica gel at 140-160 C. From polymerization of 2-phenyl-.butene-3 together with styrol copolymers with different contents of initial com- pounds were obtained. Furthermore, the condensation of benzene with glycerol in the presence of H 3PO AM FeCl3 and H2so4 was investigated. Positive reiu'lts w~rle obtained in the presence of AM at 100-102 0C and 595 - 6,0 atmospheres in the autgolave.

A report on 'this paper was given at the All-Union Conference on `,i7ays of Synthesis of Initial Prodacts for the Production of High Polymers" which took place in Yaroslavl' from September 29 to October 2, 1958. Among the polymer synthctics, gaining more and more importance, the acryl derivatives are outstanding be- cause of their many valuable properties. On the other hand, poly- mers obtained from the derivatives of acrylic and methacrylic acid esters show considerable shortcomings such as little resi- stivity to heat,wear, and crack formation. One of the ways of eliminating these shortcomings is polyncer production on the basis of the esters mentioned in the title. Only a-substituted esters can be used (Refs 1,2). After giving a survey of publications (Refs 1-9), the authors state that the synthesis of the esters Card 0 mentioned in the title in the presence of concentrated H 2so4 and Synthesis of a-Chloroacrylic Acid Esters SC. alcohol is of hi~--h rinactical interest (because the initial sub- tricthylene chloride and for.-ialdehyde are easy to obtain) (Refs 11,12). In the Paper under review, publication data on the syn thesis of methyl esters were taken into consideration, and the way of synthesis of other esters (ethyl, n.-Propyl-, iso- propyl-, n.batyl-, isobutyl-, isoamyl-, and cyclo~exyl-ester) were investibr-ated. The synthesis of the acid mentioned in the title withan exterded carbon chain has been little described in publications 'Ref 4). Acrylic acid ester, acrylon-itrile, and triethylene chloride were used as raw materials. Starting from the former, any esters can be synthesized in two sta.-es: a) synthesis of the ester of oL, P- dichloropropionic acid, b) dehydro- chlorination of dichloro derivatives obtained from propionic acid by means of various separating agents. C o n c 1 u s i o n s: 1) In the chlorination of acrylic acid esters by means of gaseous chlorine in the presence of dimethyl formamide, corresponding -dichloropropionic acid are formed with a yield eoters of UP/5 of more than 9oOO (of the theoretical yiold). 2) cxA-dichloro- propionitrile was formed by direct chlorination o acrylonitrile under the same conditions.

The medium of the organic phase consisted of n-hkotane, carbon tetrachloride, benzene, or matkWlene chloride. The mixing rate w2z 4200 rpm. It was-found that the effect of the emulsifiers depended Card: 1 ACCESSION kal: AP4032559 0111 their nature, their concentration, and'on the nature of the organic phase. Thus, in the presenc6 of s6dium. oleate, only small concentrations of the latter (0.05,-J-) and an organic phase of benzene resulted in increased molecular weight of the 2,21-bis-(4-h~droxyphenyl) propane"(11PP) polycondensate. With sodium .1aux7ylsulfate, a sixfold increase in molecular weight of IMP was obtained where benibne was the orgar4c phase, as against~.only a Urofold increase with a methylene ,chloride solvent. OP-10 yielded a polycondensate of higher molecular weight only with methylene chloride as the organic ph6e. It was found ihat an increasein molecular weight of W could be obtained only in an alkaline medium (the concen- tration used in the inirestigation amounted to 0.20 riwle/liter of NaOH). The rate oil p1hosclene hydrolysis in the process of intbrfacial polycondensation was recorded simultaneously with a determination of the amount of the Polymer dissolved in the organic phase. It was observed that the rate depended strongly on the nature of -the e-,mlsifier and of the organic phase, For example,, in the presence of sodium :lauz7lsuli~ate and n-haptaria, the expenditure of phosgene increased 3.5 times. 'The presence of an e=lsif or was also found to affect the amount of polymer i dissolved in the orgihic 1~use.

Energies of activation for the oxidations were calculated; 21.0, 17.6 and 13.0 kcal/mol, respectively. Reaction mechanisms are discussed. Auto-accelerated processes are indicated in the initial period of thermal oxidation of PK-1 and FK-2.

ABSTRACT: Physicomechanical, structural, and dielectric properties of the polycarbon- ate "ilon" films prepared from 1,1-di-(4-oxyphenyl)-cyclohexane and phosgene were studied in the temperature range from 60 to 2100C. It was found that the tensile strength of the ilon films was a function of the molecular weight of the polycarbonate The softening point of the ilon films was found to be approximately 160-1700C. It was also found that the structure of the ilon films is less regular than that of the I'diflon'l-films [diflon is a brand name of a commercial polycarbonate resin]. It was found that ilon films exhibit constant dielectric properties in the range from -60 to +1700C. It is concluded that the ilon films are superior to diflc~n films for applica- tion as dielectric films.

The second-order*transi- tion temperatures of the mixed polycarbonates changed monotonously with changes in.-i their composition, indicating. the isomorphous substitution of the main polymer link6,- in the exchange of one diphenole fortanother. The mechanical and dielectric prope of films of the mixed polycarbonate4Dwere determined. The hydrolytic resistance, of. the mixed polycarbonates obtained with 9 N NaOH is considerably higher than that of polycarbonates based on diane. Orig. art. has: 1 figure and 5 tables.

The free turbine was mounted coaxially with the com- ine (Fig., 2) but rotated indep gine pressor turb endently. The en operated in the range of 25,000 to 45,000 rpm. The.compresSor and 1- -i turbine used the full range of operational velocities;,the free' f turbine did not exceed 25,000 rpm. The experimental study was made' with an 8-stage compressor having a'rigid horizontal shaf t on two bearings - either or both.elastic or rigid. The various relation- ships derived are presented graphically in Figs. 3-5. It is shown that self-aligning conditions may be achieved by adequate deSign of the rigid and elastic bearings.\\ Self-aligning may occur in coaxial!- , rotors of any type after passing the critical speed. Ap art from the system shown in Fig. 6 of the Enclosure, other self-alignin g systems exist. It is characteristic of these systems that both bearings situated between the coaxial rotors are rigid and the mounting of the system to the-stationary turbine body secures 4 di- grees of freedom without counting the rotor revolution. In this, category of coaxial rotors, the amplitudes of vibrations increase' J Cqrd 2/&
