Title:
Method for producing methylbutinol
Document Type and Number:
Japanese Patent JP6284933
Kind Code:
B2
Abstract:
Subject of the invention is a process for the production of methylbutynol, 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 methylbutynol 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 uses and devices relating to the inventive process.
