3-***-2-羟丙基二***脱氢枞基***化铵合成研究
摘要：由脱氢枞***（DHA）和环氧***丙烷合成3-***-2-羟丙基二***脱氢枞基***化铵（CHPDMDHA）。制备过程分三步进行：首先，以脱氢枞***为主要原料通过Eschweiler-Clarke反应制得N,N-二***脱氢枞***（DMDHA）；第二步是DMDHA与盐酸反应生成N,N-二***脱氢枞***盐酸盐；最后盐酸盐与环氧***丙烷反应，并用乙酸乙酯与乙醇的复合溶剂重结晶，得到产物CHPDMDHA。用FT-IR和核磁共振表征了原料、中间体及产物的结构；离子色谱法（IC）测定了产物的含量。
结果表明，用以上方法合成CHPDMDHA时，操作简单，得到的CHPDMDHA产品与脱氢枞***及N,N-二***脱氢枞***相比具有较好的水溶性

Study on the synthesis of 3-chloro-2-hydroxypropyl dimethyl dehydroabietyl ammonium chloride
Abstract： 3-chloro-2-hydroxypropyl dimethyl dehydroabietyl ammonium chloride (CHPDMDHA) was synthesized from dehydroabietylamine (DHA) and epichlorodrin. The synthesis was done in three steps. First, DHA was transformed into N,N-dimethyl dehydroabietyl amine (DMDHA) through Eschweiler-Clarke Reaction. Second, the DMDHA was reacted with hydrochloric acid and translated into DMDHA hydrochloride. Third, the CHPDMDHA was obtained after the DMDHA hydrochloride had reacted with epichlorodrin and recrystallized using a solvent composed of ethyl acetate and ethanol. The structures of raw materials、intermediates and final products were all characterized by FT-IR and NMR. The content of intermediates and final products was analyzed by IC.
The experimental results showed that CHPDMDHA obtained by DMDHA and epichlorodrin had a good quality. The result of FT-IR and IC test showed the content of CHPDMDHA in the product was more than 85%
