相转移催化制备α-甲基肉桂醛

The Phase Transfer Catalyzed Synthesis of α Methylcinnaldehyde

首次采用相转移催化剂聚乙二醇（ＰＥＧ４００、ＰＥＧ６００）催化法，合成α甲基肉桂醛新方法，结果表明：ＰＥＧ４００ 的催化效果较好，产率达８６８１％ ，比不用催化剂提高近２０％ 。

Methylcinnaldehyde was synthesized with phase transfer catalysis polyethylene glycol(PEG).The results showed that the catalytic effect of PEG400 was the best,and the yield reached 86.81%.The purity of α Methylcinnaldehyde was 98.20% by HPLC.The structure of the product was confirmed by IR and MS.The IR spectra was according with ADTLAR standard spectra.
