Abstract:
1. A method for preparing aminoorganyltriorganylsilanes of the formula (1) comprising reacting cyclic or acyclic amines of the formula (2), with (haloorganyl)silanes of the formula (3) in which R′ is a C R R R n is 0, 1, 2 or 3, and X is chlorine, bromine or iodine, the step of reacting comprising the following steps: a) reacting the (haloorganyl)silane of the formula (3) and the amine of the formula (2) at a temperature of from 0 to 250° C., an ammonium halide of the amine of the formula (2) being formed as a byproduct in addition to aminoorganyltriorganylsilane of the formula (1), b) adding a base (B), as a result of which amine of the formula (2) is liberated and a halide of the base (B) forms, the halide of the base (B) being liquid at a temperature of not more than 200° C., and c) removing the halide of the base as a liquid from a phase containing the aminoorganyltriorganylsilanes.
