摘要
在润滑油馏分糠醛精制过程中，添加微量的十二烷基苯磺酸钠、聚醚、脂肪醇聚氧乙烯醚等表面活性剂，以改善液—液界面，从而使精制油收率比未添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)polyetheraliphatic alcohol polyoxyethylene ether respectively to furfural solvent can improve the liquid-liquid interface property during the lube distillates extracted with furfural.As a result,the yield of refined oil will increase 1.8%2.7% than not.
