摘要/Abstract

摘要： 八氯二丙醚由三氯乙烯和氯甲醚或甲醛制备。产物的结构由¹H NMR，¹³C NMR，DEPT谱、二维核磁¹³C-¹Ｈ相关谱，COSY谱、质谱、红外谱和元素分析确定。用二维核磁谱对¹HNMR谱图解析表明，氢谱为2个三旋AMX系统，与分子中存在2个不对称碳原子和体积较大的三氯甲基有关。该谱图在二级图谱中有一定代表性。

Abstract: Bis (2, 3, 3, 3-tetrachloropropyl) ether was prepared with two different ways. The structure was determined by using NMR, IR, MS and element analysis. 2D NMR was used to illustrate the complex spectrum of1 H NMR. It was found that the ¹H NMR consists of two AMX systems and that the complexity of the spectrum of ¹H NMR and ¹³C NMR is ascribed to the effect of the two chiral atoms and the blockage of the two trichloromethyl groups in the molecule.

Key words: bis (2, 3-tetrachloropropyl) ether, 2D NMR, AMS system
