使用改进的催化剂组成的直接环氧化方法

Direct epoxidation process using improved catalyst composition
摘要：
A process for producing an epoxide comprising reacting an olefin, hydrogen and oxygen in the presence of a catalyst comprising a titanium or vanadium zeolite, palladium, and lead. The process results in significantly reduced alkane by-product formed by the hydrogenation of olefin.
摘要（中）：
