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 MEK in the extract by fractional distillation and recycled to the extraction step.
L'invention concerne un procédé de récupération de méthyl-éthyl-cétone à partir d'un mélange aqueux de méthyl-éthyl-cétone et d'éthanol. Ce procédé consiste à extraire le méthyl-éthyl-cétone du mélange au moyen d'un solvant d'extraction sélectionné dans le groupe composé d'isopentane, des o-, m-, p-isomères de xylène, et de xylènes mélangés. De préférence, le solvant d'extraction est séparé du méthyl-éthyl-cétone dans l'extrait par distillation fractionnée et recyclé à l'étape d'extraction.
