中文摘要：
本文以N，N-2．Ep基苯胺、1,4-二溴丁烷为原料制备出二溴代-N，N-双（二甲基苯基）丁二胺。实验考察了该双季铵盐的合成工艺条件，从反应时间、所用溶剂、反应物之间物料比等因素对合成产物的影响，筛选出了较为适宜的反应条件。
英文摘要：
In the paper, dibromo N,N-bis （dimethylphenyl）butanediamine was prepared from N,N-dimethy- laniline and 1,4-dibromobutane as materials. The synthesis conditions of bisquats compound were inverstigated experimentally. And the method of factor was used for studying the influences of reaction time, the solvent and the molar ratio of reactant on the yield of target compound. The appropriate reaction conditions have been obtained.
