Abstract:
1. A process for preparing an alkyl-functional organosilane essentially free of chlorine, comprising contacting an alkyl-functional organosilane having a chlorine content with a basic anion exchanger to prepare the alkyl-functional organosilane essentially free of chlorine, wherein the alkyl-functional organosilane essentially free of chlorine is a siloxane derived from an alkyl-functional organosilane of formula I by hydrolysis and condensation: wherein x is =0 or 1, or the alkyl-functional organosilane having a chlorine content is a siloxane derived from an alkyl-functional organosilane of formula II by hydrolysis and condensation: wherein y=1, 2 or 3, and x=0 or 1, with the proviso that x+y in formula II is 1, 2, or 3.
