Abstract

Subject of the invention is a process for the production of methylbutinol wherein the process comprises at least one pervaporation step. In a preferred embodiment the process comprises the steps of • (a) providing a feed composition comprising methylbutinol and water • (b) subjecting the feed composition to distillation in a distillation device • (c) removing a sidestream from the distillation device the sidestream having a higher water content than the feed composition and • (d) subjecting said sidestream to pervaporation thereby reducing the water content. The invention also relates to the use of pervaporation and/or a pervaporation membrane for removing water from methylbutinol or for purifying methylbutinol.
