摘　　要：在常规的间歇萃取精馏实验装置中,研究了以蒸馏水为萃取剂间歇萃取精馏分离甲醇-丙酮共沸物的过程。考察了萃取剂、全回流时间、共沸物组成、溶剂与混合物的体积比、加盐、加碱等因素对萃取精馏分离甲醇-丙酮共沸体系的影响,从而得出最佳的萃取条件。The methanol-acetone azeotrope was separated by batch extractive distillation with distilled water as extracting agent. The effect of factors of extractant, total reflux time, azeotrope composition, volume ratio of solvent and compound, saline and alkaline on batch extractive distillation azeotrope system was investigated. The best extraction conditions were obtained.
