Liquid-phase epoxidation of allyl chloride with hydrogen peroxide was carried out over Ti-MWW, a novel titanosilicate with the MWW structure, to synthesize epichiorohydrin selectively and effectively. Ti-MWW proved to be superior to the conventional TS-1 catalyst in both catalytic activity and product selectivity. Ti-MWW prefers aprotic solvents of acetone and acetonitrile, both of which can restrain the solvolysis of epichiorohydrin, whereas TS-1 favors a protic solvent of methanol.

研究了具有MWW结构的新一代钛硅分子筛Ti-MWW催化剂对烯丙基氯液相环氧化高效合成环氧氯丙烷的催化性能结果表明，Ti-MWW的催化活性以及产物选择性均优于传统的钛硅分子筛TS-1，对于Ti-MWW，合适的溶剂为非质子性溶剂丙酮和乙腈，在该溶剂中环氧化物不易发生溶剂化开环反应；而对于TS-1，合适的溶剂是质子性溶剂甲醇，但甲醇可导致醇醚副产物的生成。

With 1-methylte-trazole-5-thiol and 7-ACA as the material and acetonitrile-boron trifluoride complex as Catalysts, 7-TMCAHCl was preparated and the yield could reach 91.80%.

以1-甲基－5-巯基四氮唑和7-ACA为原料，三氟化硼乙腈配合物为催化剂合成了7-TMCA盐酸盐，反应收率可达91.80%。

In DMSO, the polymerization of methyl methacrylate could be carried out efficiently. However the photopolymerization was inhibited in acetonitrile. It was ascribed to the complex formed between coumarin 1 and HTIB photolyzed to unreactive species after irradiation in acetonitrile.

在一般极性溶剂中如DMSO中能有效地引发甲基丙烯酸甲酯光聚合，而在电子受体性质的极性溶剂如乙腈中，光聚合反应受阻，这归结于香豆素1与羟基苯基碘鎓盐形成络合物，使得光反应后生成不具活性的产物。
