Abstract

A process for the dismutation of chlorosilanes is disclosed in which the latter are in the gas phase for 0.01-100 sec. at 55.degree.-100.degree. C. or in the liquid phase for 1-1000 sec. at 25.degree.-55.degree. C. conducted in the presence of a catalyst, which is either unformed or is present in the form of spherical pellets, and which consists of one of four different organopolysiloxane compounds, optionally cross-linked, which essentially carry an amino or ammonium group as a functional group.
