Process for the production of silanes

摘要

Silanes are produced by the disproportionation and/or redistribution reaction of chlorosilanes using a novel catalyst having a longer life and consisting of a quaternary phosphonium salt bonded to an organic macromolecule or polymer, represented by the following general formula: <IMAGE> wherein &cir& P is an organic macromolecule or polymer, A is a bridging group between phosphorus and the organic macromolecule or polymer, R1, R2 and R3 are selected from the group consisting of hydrogen, C1-C20 alkyl groups and aralkyl groups such as benzyl and phenethyl groups, which can contain oxygen or halogen atoms, and X is a halogen atom.
