摘要: 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.摘要翻译: 本发明涉及一种在活性缩合催化剂存在下,在液体反应体系中通过一种或多种醛的缩合制备α-羟基酮的方法,其中催化剂在失活时通过从其中除去水再循环至反应体系 。 二羟基丙酮是生产甘油的重要原料。
