Silicon-containing composite particles, the process comprising the steps of:

Process for preparing silicon-containing composite particles

A process for preparing trimethylchlorosilane (M3) and methyltrichlorosilane (M1) by disproportionation of dimethyldichlorosilane (M2) in the presence of an AlOcatalyst is described herein. The dimethyldichlorosilane used is in the form of a silane mixture that includes 80-100% by weight of dimethyldichlorosilane (M2). The difference in content from 100% by weight includes M1 and M3.

Process for preparing trimethylchlorosilane

A process for dehydrogenating and methylating silanes. The process includes providing methyl chloride that is reacted with a silane selected from the group consisting of SiH, HSiMe, HSiMeCl, HSiMe, HSiCl and HSiMeCl, in the presence of at least one ammonium and/or phosphonium salt at a temperature in the range of 70-350° C.

Method for the dehydrogenation and methylation of silanes with methyl chloride

Dichlorosilane and trichlorosilane are dehydrogenated at elevated temperature in the presence of an ammonium or phosphonium salt as a catalyst, and a halogenated hydrocarbon or hydrogen halide. The method may be used to synthesize organochlorosilane.

Method for the dehydrogenation of dichlorosilane

The present invention relates to a process for the production of perhalogenated hexasilane anion by reacting halogenated monosilane in the presence of organosubstituted ammonium and/or phosphonium halide at temperatures in a range from 100 to 120&#xb0; C., wherein no solvent is used, and a process for the production of a cyclic silane compound of the formula SiR, by reacting [X][SiCl] with AlRin at least one organic solvent, wherein R is chlorine or methyl and X, the same or different, is a counter-cation and is preferably selected from organosubstituted ammonium, organosubstituted phosphonium, alkali metal ions and [(PEDETA)(HSiCl)]+.
