The present invention relates to a process for preparing low-chloride or chloride-free aminofunctional organosilanes by reacting chlorofunctional organosilanes with organic amines or ammonia and separating off the organic hydrochlorides or ammonium chloride thus formed, wherein further amounts of organic hydrochlorides or ammonium chloride present are reacted by addition of metal alkoxides dissolved in alcohols and the metal chlorides formed are separated off, and also to aminofunctional organosilanes prepared thereby.
本发明涉及一种制备低氯或无氯氨基功能有机硅烷的方法,通过将氯功能有机硅烷与有机胺或氨反应,并分离所形成的有机氢氯酸盐或氨盐,其中进一步存在的有机氢氯酸盐或氨盐通过加入溶解在醇中的金属烷氧化物反应,形成的金属氯化物被分离,同时也涉及由此制备的氨基功能有机硅烷。
