| 发明名称 | Process for the production of methylbutynol | ||
| 摘要 | 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. | ||

| 主权项 | 1. A process for the production or purification of methylbutynol (2-methyl-3-butyn-2-ol), comprising the steps of (a) providing a feed composition comprising methylbutynol, water, and acetone, (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. | ||
