Process for the production of methylbutinol

摘要

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.
