摘要： 用FT-IR、Laser Raman光谱和EHMO计算研究了β-羟基酯脱水反应, 发现反应产物α、β-烯酯和β、γ-烯酯两类共轭与非共轭构异体的分布, 主要取决于β-碳上的取代甲基超共轭效应, 该反应是受动力学控制的。

Abstract: Tracing out dehydrated reaction of β-hydroxy ester by FT-IR, luster Raman spectroscopy and EHMO calculation,it is found that the distribution for products, α,β-and, β, γ-unsaturated ester is dependent on super-conjugation of substitutedm ethyl on β-carbon. And it has been proved that the reaction examined is akinetic control.
