| Abstract: | 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. |
