单乙醇胺(MEA)间歇萃取精馏甲醇-丙酮研究

Study on Batch Extractive Distillation of Methanol and Acetone by Using MEA as Extractant

用常规的间歇萃取精馏实验装置,研究了以单乙醇胺(MEA)为萃取剂间歇萃取精馏分离甲醇—丙酮恒沸物的过程。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、回流比等因素对萃取精馏分离甲醇—丙酮共沸体系的影响,从而得出最优的萃取条件。

s：Batch extractive distillation process of methanol-acetone binary azeotrope in the conventional batch extractive distillation experimental device with MEA as extracting agent was studied. Effect of extractant, total reflux time, azeotrope composition,volume ratio of solvent and mixture,reflux ratio and other factors on the extractive distillation separation of methanol - acetone azeotropic system was investigated, and the best extraction conditions were determined.
