Abstract

N-organylaminoorganyl- and N,N-diorganylaminoorganyl-triorganylsilanes are prepared continuously with high space/time yield, high product purity, and low halide content, while simultaneously increasing process safety, by introducing haloalkyltriorganylsilane and a 1 to 100 fold motor excess of organylamine into a continuous reactor with a residence time which may be less than 10 minutes, thus minimizing competing side reactions.
