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 posed 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% Keywords : Eschweiler-Clarke reaction ; 3-Chloro-2-hydroxypropyl dimethyl dehydroabietyl ammonium chloride (CHPDMDHA) ; hydrochloric acid 专业资料参考首选第一章绪论.................................................................................................................. 1 课题概述.......................................................................................................... 1 松香型表面活性剂的简介............
