TITLE- Pyrophyllite, a New Dielectric Filler for Cable Rubber PERIDDICALt Dopovidi Akademii nauk Ukra-'AnsIkoi RS)R, 1959, Nr 51 PP 489--493 (USSR) ABSTRACT.- The authors made a study of the physico-chemical properties of Ukrainian pyrophyllite of the Zbrankov deposits, Zhitomir region, with the purpose of PDplying it in cable rubbers as a dielectric filler, instead of chalk and talc (imported from the Urals). The Zbrankov pyrophyl.1--te wac, found to consist in its basic mass Of 854, of highly perse pyrophyllite mineral, about 15% quartz with trac~~3s of talc. The structural formulas of pyrophyllite and talc are as follows; pyrophyllite - Al 2 f S1 401010H)2; talc- 3M90 '4Sio-l' H2 0.

The pyrophillite found in the Ukraine was studied as a possible dielectric filler for cable rubber. Physico-chemical tests showed that it consist9d of 85% finely dispersed pyrophillite with 15% quartz and a trace of talc: The optical constants are close to those of talc. Experiments were carried out on the rubber KC -50 (K5-50) which contains 24,2% talc and 49% chAlk, It was shown that replacing either or both talc and chalk by pyrophillite had no effect on the electrical characteristics. After five days soaking in water they were practically unchanged, Similar results were obtained when pyrophillite was substituted for fillers in other rubbers, Experiments were also carried out Card 1/2 S/1.10/60/000/009/002/oo8 Eo2i/E455 Pyrophillite - A New Filler for Cable Rubbers on the rubber KS-50 to find the effect on the physico-mechanical properties of the use of pyrophillite instead of the other filleTs In particular, the stability after prolonged ageing at 120C was Lnvestigated, Very similar results were obtained by using pyrophillite, Thus, using pyrophillite in quantities up to 50 to 60% results in satisfactory properties of the insulating rubber The presence of rich sources of pyrophillite in the Ukraine have, therefore, a substantial technical and economic value- There are 6 tables and 2 Soviet references, SUBMTTTED.

The experimental :resUlts are given in Table 2- A second set of experiments was conducted by mixing the amir~es di- rectly into the raw rub-ber preparation. The results obtained 8howed a considerable improvement in the tensile strength of the rubber and twofold acceleration in reaction time. Comparison of results shows that the activity of the amines deposited on the diatomite is less than the activity of the directly admixed amines. The reduced activity in the case of the activated diatomites can be e:tplained Card 2/4 3/02 61/000/004/012/013 Use of activated diatomite ... D213 YD3 03 by the elementary structure of the diatomite and the active add*i- tive. Apparently one of the amino groups of these compounds combi- nes with the structure of the diatomite, thus reducing the availa- bility of these groups Lor. the forination. of, an, inopolysulphide com- plexes which on decomposition produce active sulphur. The greate'r activity of the directly admixed amines is, therqforet bimply e.%~_ plained by the greater concentration of the active amines which also help to accelerate the reaction. The action of the amines is to give the diatomite surface a greater affinity for the rubber. This tends'to distribute the.diatomite.,better through the mass of the rubber thus further increasing its strength. There are 3 tua- bles a~_d 3 Soviet-bloc references.

Dopovidi, no. 11, 1962, 1479-1481 TEXT: The authors studied the possibility of improving the swell ing characteristics of bentonite clays on firing, to obtain the d sired porous light-weight product uaed aB.a filler in concrete and ferroconcrete. Only few natural bentonites develop the required po- rosity in the absence of any additiveq. Ubing Kurtsevo, Cherkassy and Gorbak bentonites, it was found that swelling may be induced during.firing, by replacing the natural inorganic exchange com- plexes of montmorillonite with tetraalkylammonium cations (the al- kyl.groups being large). The beneficial action of this treatment is ascribed to the fact that the quaternary ammonium cations ad- sorbed on montmorillonite are only partially removed on heating to Card 1/2 S/021/62/000/011/011/013 The effect of ... D202/D307 400 - 5000C, leaving a layer of 0C which is then.oxidized to C02 as the temperature rises above 800 C. Owing to the low softening tem- ,perature~of montmorillonite the CO' 'md-y.-then exert a bloating ac- 2 3 tion, giving ris*e to droducts of density as low as 0.22 g/cm . The required effect may be controlled by selecting the length and. ,structure of the alkyl groups in the organic*cation.

Kondensatsiya indandiona-1,3 s diazosoyedineniyami) PERIODICAL: Zhurnal Obshchey Kjjimii, 1958, Vol. 28, 11r 1, pp,~~8-62(USSR) ABSTRACT: I. the present experiments the authors connected indandione- -1,3 with different diazotized amines an(] their derivatives. The reaction takes place most rapidly in an al1zalino, uomo- what, more slowly in a neutral and mostslowly in an acid me-- dium. But the final products are most purely obtained in an acid medium. The conversion of indandione with diaz,~~ salts in an acid medium is unknown, on the contrary it is pointed out in publications that cyclic diketones only react in this manner in an alkaline medium. The products of the conversion of indandione with diazo compounds - arylazoindandiones - are Card 1/3 crystalline compounds and difficult to dissolve in ordinary Investii-ations in the Field of Cyclic tion of Indandione-1,3 With Diazo ComDounds T n :3 - solvents, especially in glacial acetic acid, diox-ane and acetone. The table enumerates the products of the reaction of indandione with diazotized aromatic amines. 2-phenylazo- indanione-1,3 was more thoroughly investigated. It is pos. sible that the name of this compound does not correspcnd to its strtutrep as, accordina 'too published datLL, it- pos.- sesses the structure of phenylliydrazone. The authors for the present are of the opinion that phenylazoindarthone exists in two tautomeric forms (formulae I and II) which are in equilibrium. Accordinj to conditions the hydxazo- or the azo-form (I and II) reactS. In favor af formula II speaks the solubility of phenylindandione in alk-ali, under the for- mation of essolates which re-form the unchanged phenylaze-- indandione (II) on acidification. Thus the most favorable conditions for the synthesis of 2-phenylazoindandione-1,3 have been determined and a number of other 2-arylazoindand- ione-1,3 were synthesized. Some derivatives of phenylazo~ indandione-1,3 viere produced, too: p-broL-.op~ienyla--oi-ndand'~cne, p--nitrophenylazoindandione, p-sulfophenylazoindandione. the Card 2/3 monoxyn of phenylazoindandione~,. phenylhydrazone and the azine 701-1-13/63 Investigations in the Field of Cyclic Arylaz O-P-Dike tones.

In -oublications it is maintained that the nulfonation pro- cee~s over the enole form (see fcrmula M), on -which occa- sion the addition product is then formed, which finally in the hydrolysis yields the sulfonic acid in our case (see the process of reaction).

The solution of this preci- pitate in water does not show any reaction to the sulfate- -ion from which follows that the assuined inter-mediate pro- duct (II) does not fonti. It seems that thia reaction takes place im.3ediately with the 17drogen of the active raothyl ;,-xoup of indandione-1,3 that in other words the indandione joins the sulfuric-anhydride molecule under the formation of indandione-1,3-3ulfonic acid-2 (III).

TITLE: Condensation of the Sodium Salt of Ethyl Eaters of Indandione- 193-carboxylic-2-acid With Diazotized Nitroanilines PERIODICAL: Doklady Akademii nauk SSSR, 1959, Vol 126, Nr 6, pp 1182 - 1184 (USSR) ABSTRACT: There are no publication data on the interaction of indandione- 1,3-derivatives with aryl-azo compounds. If the interaction re- action of the latter with eaters of cyclohexanone-carboxylic acids is carried out in a neutral or weakly acid medium, cyclane- dion-aryl hydrazones are formed (Refs 10-12). In a strongly al- kaline medium, the'ring is disrupted# and aryl hydrazones of keto-dicarboxylic acids are formed (Refs 12-16). The authors in- vestigated the products of the condensation reaction of the o-, m-, and p-nitroanilinee mentioned in the title with the sodium salt also mentioned there. Apparently, the reaction proceeds with a displacement of the reaction center (Ref 18), not accord- ing to Dimroth's mechanism (Refs 19,20).

On heating an alcoholic solution, the corresponding 2-(nitrophenyl)-hydrazone-indandiones-193 (II, see Diagram) are formed. (II) were also obtained In an alkaline medium (pH- 8-9). The ethyl eater of the 2-(p-nitrophenyl)-azo- indandione-l,,3-carboxylic-2-acid (Ia) crystallizes from diluted ethanol with I molecule of water, and yields a monoxims. On boiling the alcoholic solution, 2-(P-nitrophenyl)-hydrazone-in- dandione-193 (II) is formed. The ethyl eater of the acid (Ia) dissolves in alkalis while the color turns into red. At the same time, the indandione ring is hydrolytically split, and the sodium salt of the ethyl ester of the p-nitrophenyl hydrazone of o-car- boxy-benzoyl-glyoxalic acid is formed. On acidification of the solution, this acid (III) is also separated in the form of a yellow precipitation. The red disodium salt (IV) of the acid (III) was isolated by heating the azo eater (Ia) with sodium ethylate in ethanol. Besides, the well water-soluble salts of the acid (III) were produced: monoammonium-, di-diethylamine-, and di- piperidine salts.
