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％。
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.
