Procedure

A glycerol-ethylene oxide-propylene oxide mixed oxyalkylate is prepared using SbCl5 catalysis by first charging a stirred autoclave with 92 g (1.0 mol) of dry glycerol and admixing, under an atmosphere of N2, 1.3 g of SbCl5 as catalyst at 40° to 60° C. To this mixture is metered in a mixture of 264 g of ethylene oxide (6.0 mol) and 264 g of propylene oxide (4.5 mol) at 60° to 80° C. in the course of 5 hours. The oxyalkylation reaction is further carried out as in Example 1.
