Abstract
Strontium-containing materials catalyze the alkoxylation of alcohols. Strontium produced alkoxylates have sharper alkoxylate distributions, lower free alcohols, lower pour points, and better detergency than alkoxylates obtained from alkali base catalysis.
Claims15
A method for the alkoxylation of alkanols comprising contacting said alkanols with a suitable alkoxylating material in the presence of a strontium-containing catalyst system comprising at least one material selected from the group consisting of strontium metal, strontium hydride, strontium oxide, strontium hydroxide, and hydrated strontium hydroxide, wherein said contacting is carried out for a sufficient time for reaction to occur to the extent desired, said reaction carried out at temperatures of from about 90.degree. C. to about 260.degree. C.
