Process of recovering methyl ethyl ketone from an aqueous mixture of methyl ethyl ketone and ethanol

摘要

A process for the recovery of methyl ethyl ketone (MEK) from an aqueous mixture of MEK and ethanol comprising extracting the MEK from the mixture using an extractive solvent selected from the group consisting of isopentane, the o-, m-, m-isomers of xylene, and mixed xylenes. Preferably the extractive solvent is separated from the MFK in the extract by fractional distillation and recycled to the extraction step.
