Organopolysiloxanes having an OH content of from 3.0-10.0 weight percent are continuously produced by continuously feeding chlorosilanes, alkoxysilanes, water, and non-polar solvent essentially non-miscible in water, continuously discharging a reaction mixture containing organopolysiloxanes dissolved in a solvent phase, and optionally separating organopolysiloxanes from the solvent phase, wherein the chlorosilanes and alkoxysilanes are added in respective weight fractions of 95-60% and 5-40% based on the total weight of chlorosilanes and alkoxysilanes. The process does not employ and polar solvents, and produces products with improved flash points while minimizing complexity and expense of waste water treatment. |
