摘要
本文以烷、酯、酮、醇四大类溶剂(包括其某些共沸物和混合物)出发,就其对润滑油馏分中油蜡的溶解特性和萃取效果的规律性作了较系统的探索,以寻找一种或数种可供替代现行酮-苯体系的溶剂。结果表明,酮-酯(丙酮-醋酸乙脂)系列的溶剂是可取的。
The ketone-benzol mixed solvent is now widely used in petroleum industry, both home and abroad. However, it is not an ideal solvent for separating wax from oil of lube distillate. For the purpose. of finding substitute solvents, the authors had made systematic study on the regularity of dissolving property and extracting effect of solvents--alkyl, ketone, ester and aleohol, including some azeotropes and their compounds. The results confirmed the desirability of ketone-ester, especially acetone and acetic ether, solvents.
