ABSTRACT:
The invention relates to a process for preparing amino-functional organosilanes which are low in chlorofunctional organosilanes or essentially free of chlorofunctional organosilanes, by reacting chloro-functional organosilanes with organic amines or ammonia and separating off the organic ammonium chlorides and/or the ammonium chloride thus formed, wherein the small amounts of chloro-functional organosilanes which have not reacted with ammonia or alkylamines are reacted by addition of at least one metal alkoxide in a reaction downstream of the aminosilane synthesis.
