Abstract
In the preparation of aminoorganylsilanes and cyclic aminosilanes by reaction of an organyl amine with a haloorganylsilane, the byproduct halide salt of the amine reactant is decomposed to amine by addition of a base whose halide salt forms a liquid phase at a temperature below 200° C., and the liquid base halide is separated from the reaction mixture.
