ABSTRACT:
This invention relates to heterogeneous (organic polymer-supported) calcium-containing 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 heterogeneous (organic polymer-supported) calcium-containing catalysts for alkoxylation using calcium oxide or calcium hydroxide as sources for the catalytically-active calcium. In a further aspect of this invention, alkoxylation products are provided that have beneficial, narrow molecular weight ranges and are essentially neutral in pH and free from catalyst residues.
