Abstract:
Silicone resins are reproducibly prepared in a four step process in which alcohol recovered in a second step is recycled to the first step, and an aqueous phase recovered in the fourth step contains very little HCl, alcohol, or organopolysiloxane, and can be directed to waste treatment without any prior processing.
