Ando催化剂催化合成α-甲基肉桂醛

SYNTHESIS OF α-METHYLCINNALDEHYDE BY ANDO’S CATALYST

采用Ando催化剂合成了α -甲基肉桂醛。其优化条件是 :以苯作溶剂 ,苯甲醛与丙醛物质的量的比为 5 :4,催化剂与反应物的质量比为 6 6 :10 0 ,反应温度为 30℃ ,反应时间 4h ,收率达89 6 % ,并且催化剂可重复使用。

Methylcinnaldehyde was synthesized with Ando's catalyst.The optimum preparation conditions are as follows:benzaldehyde:propionaldehyde is 5 mol:4 mol,catalyst:reaction materils is 6 6g:100g and reaction temperature is 30℃.Under the optimum conditions,the yield of α-methylcinnaldehyde can reach 89 6%.The catalyst could be used once more.
