METHODS FOR PRODUCING EPOXIDATION CATALYSTS AND EPOXIDATION METHODS UTILIZING THEM |
摘要 |
A method for producing epoxidation catalysts is provided. The catalyst comprises a support, a catalytic species, maganese and at least one alkali metal and/or promoter. The catalytic species may be silver. The catalyst is prepared by a method wherein at least a portion of the manganese is impregnated in a step separate from the at least one alkali metal and/or promoter. Advantageously, catalysts produced by the present method may exhibit greater efficiencies than catalysts produced by conventional methods. A method for the epoxidation of alkylenes using the catalysts so produced is provided as is a method for using the alkylene oxides for the production of 1,2-diols, 1,2-carbonates, 1,2-diol ethers, or alka-nolamines. |
