摘　　要：以松香(酸值170.54 mg/g)为原料,经与环氧氯丙烷反应,得到中间产物3-松香酰氧基-2-羟丙基氯,酯化率为99.18%,中间产物与三乙烯二胺发生季铵化反应,在n(中间产物)∶n(三乙烯二胺)1.5∶1、时间25 h、温度80℃条件下制备了二氯化-N-N′-二(3-松香酰氧-2-羟丙基)-三乙烯二胺,得率为50.71%,纯度为95.03%。采用FT-IR对产物进行了结构确证,并对其性能进行分析。结果表明:产物乳化力较强,乳化时间为10 min;产物的临界胶束浓度(cmc)为9.7×10-4mol/L,表面张力(γcmc)为43.41 mN/m;发泡能力较强,泡沫稳定性好。The CsH2 s-α,ω-bis（ abietyl hydroxy propyl triethylenediamine chloride）, here s = 2,had been synthesized by reacting 3-abietylacyloxy-2-hydroxypropyl chloride with triethylenediamine at a yield of 50.71% and purity of 95.03 %. The intermediate compound 3-abietylacyloxy-2-hydroxypropyl chloride was prepared from rosin （acid value 170.54 mg/g） reacted with epoxy chloropropane, and the esterification rate was 99.18 %. The synthesis condition of the aimed compound was as follows： n（intermediatecompound） ： n（triethylene diamines） 1.5 ： 1, reaction temperature 80 ℃ and reaction time 25 h. The structure of the aimed compound was characterized by FT-IR and its property was analyzed. The results showed that： emulsifying ability was up to 10 min, critical micelle concentration （cmc） was 9.7 × 10^-4 mol/L and surface tension was 43.41 mN. m. The aimed compound maintained strong foaming ability and superior foaming stability.
