一种1-氯-2-腈基-2-(4-氯苯基)己烷的制备方法
摘要：
本发明涉及一种1-氯-2-腈基-2-(4-氯苯基)己烷的制备方法，主要包括了1，2-(4-氯苯基)己腈的制备和1-氯-2-腈基-2-(4-氯苯基)己烷的制备两个步骤。本发明以二氯甲烷，对腈氯苯为原料，不仅降低了成本还对工艺条件进行了优化。另外本发明中对每一步进行了精馏提取不仅使产品得到了提纯大量的溶剂可以回收利用，从而使含量有了大幅度的提高。
摘要（英）：

The invention relates to a preparation method of 1-chloro -2-cyano-2-(4-chlorphenyl)hexane, which mainly comprises preparation of 1,2-(4-chlorphenyl)hexanenitrile and preparation of 1-chloro -2-cyano-2-(4-chlorphenyl)hexane. The invention takes dichloromethane and p-cyanobenzychloride as raw materials, reduces cost, and optimizes technology conditions. In addition, the invention performs rectification extraction in each step, which can purify products and recycle a large amount of solvents, thus improving the content of 1-chloro -2-cyano-2-(4-chlorphenyl)hexane greatly.
