标 题 :Process for preparing alkylchlorosilanes from the residues of direct synthesis of alkylchlorosilanes
发明人：MAUTNER KONRAD; SCHINABECK ANTON; STRAUSSBERGER HERBERT
权利人:WACKER CHEMIE GMBH
摘要:Alkylchlorosilanes are prepared continuously from the residue of direct synthesis of alkylchlorosilanes containing liquid constituents with a boiling point of at least 70 DEG C. at 1013 hPa and solid constituents, by heating the residue with hydrogen chloride at temperatures of from 300 DEG C. to 800 DEG C. in a tubular reactor with internals which can be rotated.

摘要:The subject of invention is the method of synthesis of fluorocarbofunctional alkoxysilanes and chlorosilanes of the general formula HCF 2 (CF 2 ) n (CH 2 ) m OC 3 H 7 SiR 1 R 2 R 3 in which -n takes values from 1 to 12, m takes values from 1 to 4,—R 1 stands for an alkoxy group or halogen, if R 1 stands for an alkoxy group, then R 2 and R 3 can be the same or different and stand for an alkoxy group containing C=1-4, alkyl group containing C=1-12 or an aryl group, if R 1 stands for a halogen, then R 2 and R 3 can be the same or different and stand for based on hydrosilylation of an appropriate fluoroalkyl-allyl ether with an appropriate trisubstituted silane of the general formula HSiR 1 R 2 R 3 in the presence of siloxide rhodium complex [{Rh(OSiMe 3 )(cod)} 2 ] as a catalyst.

摘要:An improved industrial method for the direct synthesis of alkylhalogenosilanes is described. Specifically, a method is described for preparing alkylhalogenosilanes by reacting, in a fluidized bed reactor, and alkyl halogenide, preferably CH3Cl, with a solid body, which is referred to as a contact body and which includes powdered silicon and a catalytic system including at least one copper catalyst and β1 and β2 promoter activities.

摘要:The direct synthesis of methylchlorosilanes to react metallic silicon with methyl chloride in the presence of a copper catalyst yields a high-boiling fraction of methylchlorodisilanes as by-products. The invention provides a method for preparing monosilanes from the high-boiling fraction by reacting it with hydrogen chloride in the presence of an amine or amide catalyst. The reaction is effected under the condition that the amount of iron, aluminum, zinc, tin and compounds thereof present in the reaction system is less than the equimolar amount with respect to the catalyst. This increases the conversion of disilanes into monosilanes.
