摘要
考察了几种路易斯酸在缩酮合成中的催化活性。在路易斯酸存在下,由丙酮与乙二醇缩合生成丙酮缩乙二醇后,再与甲醇交换,制备了丙酮缩二甲醇。
This paper reports a new preparing method of acetone dimethyl acetal by reaction of acetone with glycol to form 2,2 dimethyl 1,3 dioxolane followed by exchange with methanol,and the effect of a few kinds of Lewis acid on the yield.
