ALKOXYLATING CATALYST

PURPOSE: To produce an alkoxylated product having a narrow molecular weight range by forming a catalyst by reacting a catalyst precursor having a specified composition with a bivalent or polyvalent oxyacid or a bivalent or polyvalent metal salt of the oxyacid. CONSTITUTION: A compd. containing a biv...

Zusammenfassung:PURPOSE: To produce an alkoxylated product having a narrow molecular weight range by forming a catalyst by reacting a catalyst precursor having a specified composition with a bivalent or polyvalent oxyacid or a bivalent or polyvalent metal salt of the oxyacid. CONSTITUTION: A compd. containing a bivalent or polyvalent metal other than groups IIA or IIIB metals in the periodic table is mixed with an org. compd. having at least one active hydrogen to prepare the first bivalent or polyvalent metal-containing composition. The compd. containing the bivalent or polyvalent metal other than groups IIA or IIIB metals in the periodic table is reacted with the org. compd. having at least one active hydrogen to prepare the second bivalent or polyvalent metal-containing composition. The alkoxylation catalyst is produced by reacting the catalyst precursor obtained by reacting these first and second bivalent or polyvalent metal-containing compositions with each other under a prescribed condition, with the bivalent or polyvalent oxyacid under a prescribed condition.
