A procedure of preparation of SILANE from metildiclorosilano and TRICHLOROSILANE and - or Tetraclorosilano

摘要

A Manufacturing method of metildiclorosilano and chlorosilanes.It is characterized in that: a) in the first stage, when the redistribution between metildiclorosilano and Tetraclorosilano TRICHLOROSILANE and / or in the presence of a catalyst to form metiltriclorosilano and diclorosilano; (b) in a Second Phase, after separation from the Reaction MediumThe diclorosilano dismuta is formed in the first stage we transcuro of the presence of a catalyst to form SILANE and SILANE TRICHLOROSILANE; formed recovers and eventually the TRICHLOROSILANE is recycled to the first step.SILANE is a raw material of choice for fetch usable Silicon by decomposition, especially in Semiconductor devices or photovoltaic (solar cells).
