Abstract

Organopolysiloxanes with consistent product properties are prepared while minimizing alcohol usage in the hydrolysis of chlorosilanes by use of a vertical continuous loop reactor having a heating unit on an ascending side of the loop which is regulated such that the temperature of the reactant mixture is within ±5° C. of a set value.
