Zusammenfassung: | In the prepn. of amino-functional organosilanes (I) contg. little or no Cl by reacting Cl-functional organosilanes (II) with organic amines (III) or NH2 and sepg. the resultant organic hydrochloride (IV) or NH4Cl, the novelty is that the (IV) or NH4Cl present is reacted by adding metal alkoxide (V) dissolved in alcohol and the resultant metal chloride is sepd. Also claimed are (I) prepd. and purified in this way. |
