通过分步组装和原位组装两种方式实现了Sharp less试剂在中孔载体HMS上的固相化。FT -IR表征表明 ,两种组装方式得到的样品的键合模式基本一致 ,DET通过—OH和键连在HMS上的钛化合物的酯基发生交换而被键合 ;低温条件下的组装样品钛含量较高 ,催化环氧化性能较好 ;样品经重复使用 3次后 ,催化性能基本保持稳定。 The solidification of Sharp less reagent on mesoporous support HMS was achieved by two steps of assembly and in situ assembly. FT-IR characterization showed that the bonding modes of the samples obtained by the two assembly methods were basically the same. DET was bound through the exchange of -OH and the ester groups of the titanium compounds bonded to the HMS; the titanium Higher content, good catalytic epoxidation performance; the sample after repeated use of 3 times, the catalytic performance remained stable.
