    • 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.
    • 制备式(I)R(R')-Y-Si(R 1)n(OR 2)3-n(I)的烷基氨基 - 烷基烷氧基硅烷的方法,其中R是具有1 至12个碳原子,R'为氢(H)或为具有1至12个碳原子的直链,支链或环状烷基,Y为-CH 2 - , - (CH 2)2 - , - (CH 2)3 - , - (CH 2)(CH(CH 3))(CH 2) - 和 - (CH 2)4 - ,R 1和R 2相同或不同, 通过使过量使用的烷基胺蒸馏出过量的游离烷基胺,将剩余的产物混合物与烷基氨基烷基烷氧基硅烷一起处理并处理,使n为0或1或2。
