Abstract:
1. A method (I) for producing an aminoorganyltriorganylsilane of the general formula (1) by reacting a cyclic or acyclic amine of the general formula (2), with a (haloorganyl)silane of the general formula (3) in which R′ is an acyloxy radical or an alkoxy radical having in each case 1-10 C atoms, R R R R n is a number equal to 0, 1, 2 or 3 and X is chlorine, bromine or iodine, the reacting comprising the successive steps: a) reaction of 1.1 to 100 mol of the amine of the general formula (2) per mole of the (haloorganyl)silane of the general formula (3) in a reaction mixture at a temperature of from 0 to 250° C., an ammonium halide of the amine of the general formula (2) being formed as a byproduct in addition to the silane of the general formula (1), b) addition of a base (B) to the reaction mixture, wherein the base (B): c) distillation of the amine of the general formula (2) out of the reaction mixture, d) addition of base (B) to the reaction mixture in an amount sufficient to form two liquid phases, one phase containing at least 90% by weight of a hydrohalide of the base (B) and e) removal of the liquid phase which contains at least 90% by weight of the hydrohalide of the base (B).
