摘　　要：以七氯丙烷为原料,合成了氯化消毒副产物——2,2,4-三氯-5-甲氧基-环戊-4-烯-1,3-二酮(TCM-CD),总收率为13%,产品纯度在98%以上.通过质谱、核磁共振、红外光谱等对TCMCD进行表征,进一步确认了副产物的结构.A newly found chlorination disinfection by-product- 2,2,4-trichloro-5-methoxy-cyclopent-4-ene-1,3- dione（TCMCD） has been synthesized from heptachloropropane, the overall yield is 13% , and the purity of the product is above 98%. The output obtained by the method of synthesis characterized by MS, ^1H NMR, ^13C NMR and IR, which further confirms the structure of the new disinfection by-product, and the result indicates that the structure we former proposed is correct.
