Alkoxylation using modified calcium-containing bimetallic or polymetallic catalysts
This patent describes a method for providing an alkoxylation catalyst. It comprises reacting or solubilizing, at least partially, calcium metal or a calcium-containing compound, by mixing with an activator or solubilizing thereby forming a calcium-containing reacting a divalent or polyvalent metal or a divalent or polyvalent metal-containing compound wherein the divalent or polyvalent metal is selected from the group consisting of beryllium, magnesium, strontium, barium, lanthanum, titanium, zirconium, hafnium, niobium, tantalum, molybdenum, tungsten, iron, cobalt, nickel, copper, zinc, boron, gallium, silicon, germanium tin, phosphorus, antimony, sulfur, selenium, tellurium, cerium and thorium with an organic compound having at least one active hydrogen to produce a divalent or polyvalent metal-containing composition: reacting the calcium-containing composition with the divalent or polyvalent metal-containing composition under effective reaction conditions to produce a catalyst precursor composition; and reacting the catalyst precursor composition with a divalent or polyvalent oxyacid or a divalent or polyvalent metal salt of an oxyacid or mixtures thereof under effective reaction conditions to produce the alkoxylation catalyst.
