ABSTRACT:
Organopolysiloxanes are prepared in a multistage process by a first partial hydrolysis with from 0.002 to 0.6 mol water per hydrolyzable chlorine and alcohol at a water to alcohol ratio of 0.001 to 1.5, then further hydrolyzing with additional water, and then separating an aqueous alcoholic phase from an organopolysiloxane phase.
