PROCESS FOR PREPARING ORGANOSILOXANES

摘要

An improved process is provided for preparing organosiloxanes and alkyl halides by passing organohalosilanes and alkanols having 1 and/or 2 carbon atoms through at least one layer of packing material which is maintained at a temperature of from 60 to 150.degree.C. The improvement comprises (1) recycling from 1 to 6 liters of an aqueous phase separated from the organosiloxanes emerging from the layer or layers of packing material for each mol of organohalosilane introduced into the layer or layers of packing material and (2) reacting the organosiloxane separated from the aqueous phase with from 2 to 10 percent by weight based on the weight of the organosiloxane with the same organohalosilane which is passed through the layer or layers of packing material. This process permits greater space-time yield economy.
