Abstract

Abstract Alkanol alkoxylates having utility, for instance, as nonionic surfactants in detergent formulations are prepared by the reaction of C 1 to C 30 alkanols with C 2 to C 4 alkylene oxides in the presence of a catalytically effective amount of a co-catalyst combination comprising as a first component one or more soluble, basic compounds of magnesium and as a second component one or more soluble compounds of at least one element selected from the group consisting of aluminum, boron, zinc, titanium, silicon, molybdenum, vanadium, gallium, germanium, yttrium, zirconium, niobium, cadmium, indium, tin, antimony, tungsten, hafnium, tantalum, thallium, lead, and bismuth.
