Abstract

Process for the production of organosiloxanes comprising contacting (A) at least one organosilicon compound having in the molecule at least one silanol group, the organic substituents being selected from monovalent hydrocarbon groups having from 1 to 14 carbon atoms and monovalent substituted hydrocarbon groups having from 1 to 10 carbon atoms, with (B) one or more compounds selected from rubidium carbonate, cesium carbonate and carboxylates of rubidium and cesium.
