Procedure

1 mole of glycerol, 4 moles of trimethylchlorosilane and 0.003 moles of trimethylbenzyl ammonium chloride were reacted at the reflux temperature (54°-102° C.) as in Example 1. Excess silylating agent was distilled off after termination of the reaction. The catalyst was filtered off when the reaction mixture was cold.
