Abstract
Alkanol alkoxylates having utility, for instance, as nonionic surfactants in detergent formulations are prepared by the reaction of C.sub.6 to C.sub.30 alkanols with C.sub.2 to C.sub.4 alkylene oxides in the presence of a catalytically effective amount of one or more soluble basic compounds of magnesium and additionally in the presence of as a reaction activator at least about 2 percent by mole, calculated on moles of alkanol, of alkoxylates of one or more C.sub.1 to C.sub.30 alkanols having in the alkoxylate molecules from one to about 30 adducts of one or more alkylene oxides selected from the class consisting of C.sub.2 to C.sub.4 alkylene oxides.
