摘　　要：以乙烯焦油为原料,盐酸三乙胺三氯化铝离子液体为催化剂,利用空气催化氧化制备道路沥青。利用单因素实验分析了所得沥青产品的针入度、延度、软化点随催化剂加入量、反应时间和温度变化的规律。确定了最佳工艺条件为:催化剂用量为焦油质量的1.5%,反应温度为170℃,反应时间为1.5 h,反应过程的空气流量为300 m3/(h·t),产物沥青的收率为92%以上。红外和核磁共振氢谱表明乙烯焦油发生了催化氧化聚合反应。经检测所获得沥青产品的质量完全满足GB/T 15180—2010要求。A novel process based on air catalytic oxidation method with ethylene tar as raw material and Et3 NHCl- AlCl3 as the catalyst is used to produce asphalt for pavement. Single factor experiment design is employed to evaluate the effect of catalyst input, reaction temperature and reaction time on penetration, softening point, ductility of the asphalt product. The optimal preparation condition is determined as follows ： 1.5% of the mass of ethylene tar as catalyst, 170℃ of the reaction temperature, 1.5 hours of the reaction time and 300 m^3/h· t of the air flowrate. The yield of asphalt is more than 92%. The asphalt products are identified by the FT-IR and NMR analysis. The results indicate that the ethylene tar has been oxidized and polymerized during the process. The properties of the product are in agreement with the standard of GB/T 15180-2010.
