    摘要: 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.

    摘要: Alkylene oxide adducts of organic compounds having active hydrogen atoms are prepared by a process which comprises contacting and reacting an alkylene oxide reactant comprising one or more vicinal alkylene oxides with an active hydrogen containing reactant comprising one or more compounds having active hydrogen atoms in the presence of a catalyst which comprises one or more compounds comprising a rare earth element and phosphorus supported on an inert porous support. The product alkoxylates are known to be useful, for instance, as nonionic surfactants, wetting and emulsifying agents, solvents, and chemical intermediates.
