2-氯乙酸酯化反应的Ingold-Taft方程

Ingold-Taft Equation of the Esterification of 2-Chloroacetic Acid with Alcohols

在有无硫酸铁水合物催化剂的情况下,分别测定了2-氯乙酸与六种伯醇的酯化反应速率常数;确定了十个Ingold-Taft线性自由能方程,实验结果表明硫酸铁水合物对酯化反应有明显的催化效果。

The rate constants of esterification of 2-chloroacetic acid with 6 species of the primary alcohols were determined in the presence of and in the absence of catalyst, the hydrate of ferric sulphate.The linear free energy equation is established according to data of the rate constants and the constants of polar Substituting groups σ^(?). The results show that ferric sulfate hydrate is effecient as the catalyst of esterification.
