摘　　要：从歧化松香胺中分离提纯去氢枞胺,然后以去氢枞胺为原料,经N,N-二甲基去氢枞胺中间体,合成了N-去氢枞基-N,N-二甲基羧甲基甜菜碱及其氯化物这两种新型甜菜碱类两性表面活性剂。通过紫外、红外及质谱分析,对产品进行了结构表征,并测定了氯化物产品的表面张力和临界胶束浓度。Dehydroabietylamine was separated from disproportionated rosin amine and purified. Then, two novel betaine-type amphoteric surfactants,N-dehydroabietyl-N,N-dimethyl carboxymethyl betaine and its chloride, were synthesized from the intermediate N,N-dimethyl dehydroabietylamine. The structures of the target products were characterized by UV, IR and MS spectroscopy. Furthermore, the surface tension and critical micelle concentration (CMC) of the chloride were determined.
