固体碱催化合成假性紫罗兰酮

SYNTHESIS OF PSEUDO-IONONE WITH SOLID-BASE CATALYSTS

系统地研究了各种固体碱催化剂催化柠檬醛与丙酮缩合制备假性紫罗兰酮的反应活性及选择性,用氢氧化钡或大孔强碱性阴离子交换树脂催化,产品收率高达95％。

Various solid-base catalysts were used in the condensation of citral with acetone,and the reactive activity and selectivity were well examined. Using barium hydroxide or basic ion exchanger,the yield of the reaction was up to 95%.
