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:Disclosed herein is a catalytic process for the synthesis of organohalosilane monomers from tetraorganodihalodisilanes and other compounds that are not cleaved during the conventional hydrochlorination of Direct Process Residue. The process is characterized by the use of a catalyst containing (1) one or more heterocyclic amines and/or one or more heterocyclic ammonium halides, and (2) one or more quaternary Group 15 onium compounds.

摘要:The invention relates to a process for preparing alkylchlorosilanes from the liquid constituents of the residues from the direct synthesis of alkylchlorosilanes which have a boiling point of above 70° C. at 1013 hPa and comprise disilanes, in which the residues are heated with hydrogen chloride and silicon at temperatures of at least 300° C., with at least 10% by weight of trichlorosilane and/or tetrachlorosilane, based on the weight of the alkylchlorosilanes formed, being formed at the same time.

标 题:Synthesis of chloromethyldisilanes
发明人：GORDON ROY G
权利人:GORDON ROY G
摘要:1,2 Dichloro-1,1,2,2-tetramethyldisilane is synthesized in high yield and good purity starting from a crude mixture of chloromethyldisilanes formed as by-products in the manufacture of silicones. The new method uses less than half as much Grignard reagent as previous methods required. The synthesis can also be used to produce other haloalkyldisilanes such as chloropentamethyldisilane or 1,1,2 trichloro-1,2,2-trimethyldisilane.
