用β-环糊精构筑新型催化剂

The New Catalyst Constructed by βCyclodextrin Derivant

用β－环糊精二间羧基苯磺酸酯同三氯化铁形成配合物，在Ｎ，Ｎ－二甲基甲酰胺介质中与过氧化氢构筑模拟酶，作为新型催化剂体系，将苯胺氧化生成硝基苯，其催化反应速率是ＦｅＣｌ３＋Ｈ２Ｏ２的９１倍，是配合物的６３倍。

A mimic enzyme was constructed by hydrogen peroxide and a complex, which was prepared from βcyclodextrin, mcarbonyl benzenesulfonyl chlorid and iron trichloride, in N,Ndimethylformamid. Aniline can be oxidized to nitrobenzene by the enzyme 91 times as fast as by FeCl3+H2O2 and 63 times as fast as by the complex alone.
