摘　　要：采用N-十八烷基-1,3-丙撑二胺、丙烯酰胺、氯乙酸、氢氧化钠和异丙醇为原料,通过两步反应得到了一种新型沥青乳化剂.第二步反应的最优条件为:摩尔比(氯乙酸钠/N-十八烷基-1,3-丙撑二胺)为2.20,反应温度为70℃,反应时间为4 h,产率为67.22%.采用FTIR、1H NMR和元素分析对沥青乳化剂的化学结构进行了表征.产物的临界胶束浓度为6.76×10^(-4) mol/L,此时的表面张力为47.89 mN/m.该表面活性剂为中裂型沥青乳化剂.A novel asphalt emulsifier was synthesized by two-step reactions using N-octadecyl-1,3-diaminopropane,acrylamide,chloroacetic acid,sodium hydroxide and isopropyl alcohol.The optimum reaction conditions for the second step were as follows:the mole ratio(sodium chloroacetate to N-octadecyl-1,3-diaminopropane)was 2.20,the reaction temperature was 70℃,the reaction time was 4 h,and the yield is 67.22%.The chemical structure of asphalt emulsifier was characterized by FTIR,1H NMR and elemental analysis.The CMC of the product was 6.76×10^(-4) mol/L,and the surface tension at CMC was 47.89 mN/m.The surfactant is a medium-set asphalt emulsifier.
