将三氯乙烯、甲苯、二氯甲烷、1,1,1-三氯乙烷、四氯乙烯、正溴丙烷、D-柠檬烯及超临界CO2 流体再生沥青混凝土萃取溶剂的萃取性能进行对比研究. 研究结果表明:D-柠檬烯的碳氢化合物溶剂能力较差,萃取速度较慢;三氯乙烯、1,1,1-三氯乙烷、二氯甲烷与正溴丙烷的萃取速度相近;1,1,1-三氯乙烷有最高的ODP(臭氧消耗潜能)值,D-柠檬烯的ODP值为零;三氯乙烯、1,1,1-三氯乙烷、正溴丙烷、甲苯及D-柠檬烯的GWP(全球暖化潜在指标)值分别为140、12、8. 7、1. 57、2. 5和0;若以超临界CO2 流体作为干洗溶剂,可节省资源、减少碳排放,是一种环保型的沥青萃取溶剂.

This paper performs comparative research on extracting properties of trichloro ethylene, methylbenzene, 1, 1, 1 - trichloroethane, tetrochloroethylene, propyl bromide, D - limonene and supercritical CO2 fluid regenerating asphalt concrete extracting solvents. The results of research show that the ability of hydrocarbon solvent of D-limonene is inferior and extracting speed is slow;extracting speeds of trichloro ethylene, 1,1,1 -trichloroethane, dichloromethane and propyl bromide are close; 1,1,1 -trichloroethane exhibits the highest ozone-destroying potential ( ODP) , the ODP value of D-limonene is zero;the global warming potential ( GWP) index values of trichloro ethylene, 1,1,1 -trichloroethane, propyl bromide , methylbenzene and D-limonene are 140 , 12 , 8 . 7 , 1 . 57 , 2 . 5 and 0 , respectively;supercritical CO2 fluid if taken as dry cleaning solvent can save resources and reduce carbon emission and is an environment friendly asphalt extracting solvent.
