Abstract
Abstract Isopropyl ether (IPE) cannot be completely separated from its mixtures with methyl ethyl ketone (MEK) by distillation because of the presence of the minimum binary azeotrope. However these two can be readily separated by using extractive distillation in which the extractive distillation agent is a higher boiling oxygenated, nitrogenous and/or sulfur containing organic compound or a mixture of these. Typical examples of effective agents are: ethylene carbonate; adiponitrile and 1,4-butanediol; sulfolane, dimethyl-sulfoxide (DMSO) and triethylene glycol.
