Abstract
Strontium and barium-based catalyzed alkoxylation of alcohols of all classes is carried out more rapidly and produces a more peaked reaction product when carried out in the presence of co-catalysts such as calcium oxide, calcium carbide, calcium hydroxide, magnesium metal, magnesium hydroxides, zinc oxide, and aluminum metal.
Claims22
A method for the alkoxylation of alcohols containing from about 2 to about 36 carbon atoms, comprising carrying out said alkoxylation by contacting said alcohols with an alkoxylating agent in the presence of basic strontium-containing or barium-containing materials together with an effective amount of an inorganic co-catalyst selected from the group consisting of calcium oxide, calcium carbide, calcium hydroxide, magnesium metal, aluminum metal, zinc oxide, and magnesium hydroxide, and wherein the alkoxylation reaction is carried out at temperatures of from about 120.degree. C. to about 260.degree. C.
