Document Type and Number:

WIPO Patent Application WO/1984/002517

Kind Code:

A1

Abstract:

A process for preparing silanes by reducing polyhalosilane using a mixture of alkylaluminum hydride and trialkylaluminum as a reducing agent, which comprises conducting the reduction after treating the mixture so as to remove trialkylaluminum in such an amount that its content becomes at most 10 mol % of alkylaluminum hydride. The removal of trialkylaluminum from the mixture is effected by, for example, distillation, recrystallization, complex formation, thermal decomposition of trialkylaluminum, or hydrogenolysis.
