Abstract
For the preparation of organopolysiloxanes, water glass diluted with water to a concentration of 3 to 15 wt % is reacted with a triorganohalosilane in the presence of an acid and an oxygen-containing solvent such as isobutyl alcohol, methyl isobutyl ketone or 1-pentanol. The invention achieves a considerable reduction of the environmental load, an improved utilization of reactants, an improved yield, and a cost reduction, and enables production of low viscosity MQ resins.
