Claim:
A process for the production of (N-organylaminoorganyl)- and (N,N-diorganylaminoorganyl)triorganylsilanes of the formula (1) R 3-n R 1 n Si—R 2 —NR 3 R 4 (1) by reacting cyclic or acyclic amines of the formula (2) H—NR 3 R 4 , (2) whose water content is from 0 to 20,000 ppm, with (haloorganyl)silanes of the formula (3) R 3-n R 1 n Si—R 2 —X (3) in which R are a C 1-10 hydrocarbon or C 1-10 alkoxy radicals which are saturated or unsaturated, branched or straight-chain, substituted or unsubstituted, R 1 is a C 1-10 hydrocarbon radical which is saturated or unsaturated, branched or straight-chain, substituted or unsubstituted, R 2 is a C 1-10 hydrocarbon radical which is saturated or unsaturated, branched or straight-chain, substituted or unsubstituted, R 3 ,R 4 are hydrogen or a C 1-10 hydrocarbon radical which is saturated or unsaturated, branched or straight-chain, substituted or unsubstituted, wherein R 3 , R 4 are identical or different and are optionally linked to one another to form a ring structure optionally containing one or more heteroatoms, and at least one of R 3 and R 4 is not hydrogen, X is chlorine, bromine or iodine and n is a number equal to 1, 2 or 3, the process comprising the steps of a) continuously adding (haloorganyl)silane of formula (3) over a period of from 1 to not more than 3 hours at a temperature of from 80° C. to 200° C., to a 3- to 6-fold stoichiometric excess of amine of the formula (2), which was initially present and heated to the reaction temperature, b) introducing ammonia during or after the addition of the (haloorganyl)silane to commence double decomposition of hydrohalides, c) removing of ammonium salts formed in step b) after the end of the addition, and d) removing excess amine after the end of the addition.
