摘　　要：本文利用相转移催化剂十六烷基三甲基溴化铵(CTMAB)催化合成苄叉丙酮,最佳反应条件为:醛酮摩尔用量比为1:2,反应时间为40min,催化剂的用量为2.5g,收率达94.6%。实验证明,相转移催化合成对该反应是高效、低成本和实用的方法。Use of CTMAB as phase transfer catalyst on the synthesis of benzalacetone was studied. The optimized conditions were following： the mole ratio of benzaldehyde to acetone was 1：2, the reaction time was 40min and the weight of phase transfer catalyst was 2.5g. The chemical yield was 94.60% .Experiment results showed that phase transfer catalyt（CTMAB） was highly active catalyst for this reaction. It is an inexpensive and very practical method.
