, said reaction comprising the following steps: a) reacting the (haloorganyl)silane of the general formula (3) and the (aminoorganyl)silane of the general formula (2) at a temperature of 0 to 250° C. to form, as well as the silylorganoamine of the general formula (1), the ammonium halide of the (aminoorganyl)silane of the general formula (2) as a by-product, b) adding a base (B), which results in complete or partial ester interchange, in which the (aminoorganyl)silane of the general formula (2) is released again and forms the halide of the base (B), the halide of the base (B) being liquid at temperatures of at most 200° C., and c) removing the liquid halide formed from the base (B).
该发明提供了一种制备通式(1)R′3-nR1nSi-R2-NR3-R4-SiR″3-mR5m的硅烷有机胺的方法,其中通过将通式(2)H-NR3-R4-SiR″3-mR5m的氨基有机硅烷与通式(3)R′3-nR1nSi-R2-X(3)的卤代有机硅烷反应来实现,其中R′、R″、R1、R2、R3、R4、R5、X、m和n分别如权利要求书中所定义,该反应包括以下步骤:a)在0至250℃的温度下反应通式(3)的卤代有机硅烷和通式(2)的氨基有机硅烷,形成通式(1)的硅烷有机胺以及通式(2)的氨基有机硅烷的铵卤化物作为副产物,b)加入碱(B),导致完全或部分酯交换,其中再次释放通式(2)的氨基有机硅烷并形成碱(B)的卤化物,该卤化物在最高200℃的温度下为液态,c)除去从碱(B)形成的液态卤化物。
