Abstract: Cpds. of formula: Z-alk-Sn-alk-Z (I) (where Z is -Si(R1)2R2, -SiR1(R2)2 or -Si(R2)3; R1 is 1-4 C alkyl or Ph; R2 is 1-8 pref. 1-4 C alkoxy, 5-8 C cycloalkoxy or 1-8 C alkylmercapto; alk is 1-18 pref. 1-6 esp. 2-3 C (cyclo)alk(en)ylene; n is 2-6 pref. 2-3 or esp. 4) are prepd. by continuously reacting 2 moles Z-alk-hal (where hal is Cl, Br or I) with 1 mole M2Sn (where M is NH4 or a (pref. alkali) metal, esp. Na). (I) are known rubber adjuvants, which improve the static and dynamic props. of the vulcanised prod.

Abstract: Hydrogen containing chlorosilanes, preferably trichlorosilanes, are prepared by reacting silicon tetrachloride with hydrogen at a temperature of 600 DEG -1200 DEG C. with a SiCl4/H2 mixture having a molar composition between 1:1 and 1:50 in equilibrium with SiHCl3 and HCl and suddenly quenching the mixture to below 300 DEG C.

Abstract: Sulphur-contg. organosilicon cpds. Z-Alk-Sn-Alk-Z (I) (where Z =Si(R1)(R1)(R2) - Si(R1)(R2)(R2) or -Si(R2)(R2)(R2), R1 = 1-4C alkyl or phenyl, R2 = 1-8C (esp. 1-4C) alkyl or 5-8C cycloalkyl or 1-8C straight or branched alkylmercapto gp. Alk = opt. unsatd. straight or branched opt. cyclic 1-18C (esp. 1-6C or pref. 2 or 3C) hydrocarbon gp. and n = 2-6) are prepd. by reacting 2 mols. of a cpd. Z-alk-Hal where Hal = Cl, Br or I with 1 mol. of a cpd. Me2Sn in which Me = ammonium or metal atom, esp. alkali metal such as Na, pref. in an org. solvent such as acetone or an alcohol, at elevated temps. followed by filtering off the metal halide formed and distillation of the solvent under reduced pressure to leave the (I) as residue.

Abstract: Shaped bodies of a molecular sieve zeolite having an improved mechanical hardness greater than 5 kp are produced by spraying an unstable silicic acid sol as the binder on to a zone of the rotating plate of a granulating device and concurrently applying the pulverized zeolite particles to another zone of the rotating plate, while avoiding the formation of a plastic mass, and the thus produced shaped bodies are dried and activated according to the disclosed process. The unstable silicic acid sol has a silicic acid content greater than 10 percent by weight and a BET surface greater than 150 m2/g.

Abstract: The present discovery concerns new organosilanes which possess two silane groups, one of which is located at each end of a polymeric molecule. These compounds are useful in improving the physical properties of synthetic thermoplastic materials which are based on formaldehyde or trioxane and inorganic solids.

Abstract: 1277592 Germanium dioxide DEUTSCHE GOLDUND SILBER-SCHEIDEANSTALT 4 Sept 1969 [20 Sept 1968] 43879/69 Heading C1A Amorphous highly dispersed germanium dioxide is prepared by reacting a volatile tetravalent germanium compound or a sprayable solution thereof under hydrolysing or oxidizing conditions in the gas phase or as an aerosol at a temperature above 1300 C., allowing the germanium dioxide formed to coagulate at a temperature of from 200 to 1000 C., and separating the gaseous reaction products. The germanium compound is preferably a halide or a volatile organo-germanium compound. The reaction is preferably carried out at a temperature of from 1400 to 1700 C. using a fuel gas of high calorific value with a free oxygen containing gas or pure oxygen, the mixture being reacted after passage through a nozzle. The germanium dioxide formed is preferably coagulated and separated at a temperature of from 400 to 700 C.
