ABSTRACT:
Active-hydrogen compounds, for example, primary and secondary alcohols or diols, are alkoxylated, for example, ethoxylated, using solid anion-bound metal oxide catalysts, such as, zirconium oxysulfate catalyst. Hydrous zirconium oxide is treated with solutions of sulfate phosphate, nitrate or tetrafluoroborate and calcined in air at 300.degree. to 950.degree. C. to produce highly active heterogeneous alkoxylation catalysts. The amorphous catalysts afford narrow molecular weight products. The catalyst can be removed from the product by filtration and reused with no significant loss in activity. Reaction temperatures of 50.degree. to 140.degree. C. are employed for alkoxylation.
