Process for converting certain lactones to their alpha-methylene substituted forms that not only exhibits high initial activity (conversion), but also provides high reactor productivity (mass of product per mass of catalyst per unit of time) and sustained maintenance of a high level of activity and productivity with time on stream.
将某些内酯转化为其α-亚甲基取代形式的过程不仅表现出高初始活性(转化率),而且提供高反应器生产率(单位时间内的产品质量与催化剂质量之比)并且在运行时间上保持高
水平的活性和生产率。
