Abstract:
1. A process for preparing N-(organylaminoorganyl)- and (N,N-diorganylaminoorganyl)triorganylsilanes of the formula (1) where R is a hydrocarbon radical or an alkoxy radical which has 1-10 carbon atoms and is saturated or unsaturated, branched or unbranched, substituted or unsubstituted, R R R X is chlorine, bromine or iodine, n is equal to 1, 2 or 3 and the process comprising continuously reacting cyclic or acyclic amines of the formula (2) which have a water content of from 0 to 20,000 ppm with (haloorganyl)silanes of the formula (3) in the steps of: a) uniformly adding the (haloorganyl)silane of the formula (3) and the amine of the formula (2) to a continuous reactor at a temperature of from 50 to 250° C., the residence time of the reactants in the reactor being between 1 min and 120 min and the amine of the general formula (2) being used in a 1- to 100-fold molar excess, and b) adding at least one nitrogen compound which forms a removable liquid or solid adduct with hydrogen halides and removing adducts formed therewith.
