ABSTRACT:
This invention relates to modified calcium-containng catalysts and the use thereof in the preparation of alkoxylation products, i.e., condensation reaction products of alkylene oxides and organic compounds having at least one active hydrogen. In another aspect of this invention, processes are provided for preparing modified calcium-containing catalysts for alkoxylation using calcium metal or a calcium-containing compound, e.g., calcium oxide or calcium hydroxide, as sources for the catalytically-active calcium and at least one divalent or polyvalent metal salt of an oxyacid as a modifier. In a further aspect of this invention, processes are provided for preparing alkoxylaton products that have beneficial, narrow molecular weight ranges using the modified calcium-containing catalysts.
