This invention relates to a process for producing alpha-hydroxy ketones by condensation of one or more aldehydes in a liquid reaction system in the presence of an active condensation catalyst wherein the catalyst upon deactivation is reactivated by removal of water therefrom and recycled to the reaction system.
Dihydroxyacetone is a vital raw material for the production of glycerol.
本发明涉及一种在有活性缩合催化剂存在的液体反应体系中通过缩合一种或多种醛来生产α-羟基酮的工艺,其中催化剂在失活后通过去除其中的
水而重新活化,并循环到反应体系中。
二
羟基丙酮是生产
甘油的重要原料。
