以糠醛、糠醛与表氯醇混合溶剂分别对大庆油田化工总厂的润滑油馏分进行精制实验。实验的结果表明 ,糠醛与表氯醇混合溶剂的精制过程比糠醛精制过程优越 ,在精制油质量相当的情况下 ,混合溶剂不仅降低了精制温度 ,提高了精制油收率 ,而且降低了精制过程的能耗和剂耗。 Furfural, furfural and epichlorohydrin mixed solvents were Daqing Oilfield Chemical Plant Lubricant distillate purification experiments. The experimental results show that the purification process of furfural and epichlorohydrin mixed solvent is superior to the furfural refining process. When the quality of refined oil is equivalent, the mixed solvent not only reduces the refining temperature, increases the yield of refined oil, but also reduces the refining process The energy consumption and consumption.
