【摘要】 在润滑油馏分糠醛精制过程中,分别添加微量十二烷基磺酸钠、聚醚、脂肪醇聚氧乙烯醚等表面活性剂,改善液——液界面性质,使精制油收率比未加表面活性剂时提高1.8—2.7％。更多还原

【Abstract】 It has been found that adding the trace amount of surface active agent such as sodium dodecyl benzene sulfonate(SDBS), polyether, aliphatic alcohol polyxoyethylent ether respectively in furfural solvent can improve liquid - liquid interface property in the process of furfural refining. As a result, the yield of refined oil will increase 1.8-2.1% than not.更多还原
