Abstract

A process for preparing an alkylamino-alkylalkoxysilane of formula (I) R—(NR′)—Y—Si(R1)n(OR2)3-n (I) in which R is a linear, branched or cyclic alkyl group having 1 to 12 carbon atoms, R′ is a hydrogen (H) or is a linear, branched or cyclic alkyl group having 1 to 12 carbon atoms, Y is a bivalent alkyl group from the group of —CH2—, —(CH2)2—, —(CH2)3—, —(CH2)(CH(CH3))(CH2)— and —(CH2)4—, R1 and R2 groups are the same or different and are each a linear or branched alkyl group having 1 to 4 carbon atoms, and n is 0 or 1 or 2, by reacting an alkylamine, used in excess, distilling off excess free alkylamine, treating the remaining product mixture with the alkylaminoalkylalkoxysilane and working up.
