| 发明名称 | Epoxidation methods | ||
| 摘要 | A method for the epoxidation of alkylenes is provided. The method makes use of an epoxidation catalyst comprising a support, silver, manganese and greater than 35 ppm sodium. The catalyst is produced by a method comprising impregnating the support with manganese prior to impregnating the support with sodium and impregnating the support with silver prior to, at the same time as, or after impregnation with manganese. A method for using the alkylene oxides for the production of 1,2-diols, 1,2-carbonates, 1,2-diol ethers is also provided. | ||

| 主权项 | 1. A method for the epoxidation of one or more alkylenes comprising contacting one or more feed streams comprising an oxygen source and an alkylene in the presence of an epoxidation catalyst, wherein the epoxidation catalyst comprises a support, silver, manganese and greater than 35 ppm sodium, and is prepared by a method comprising: Impregnating the support with manganese prior to impregnating the support with sodium; and Impregnating the support with silver prior to, at the same time as or after impregnation with manganese. | ||
