摘　　要：苯磺酸甲酯醇解反应的动力学研究赖国华，胡科诚，金松寿（杭州大学化学系杭州３１００２８）关键词动力学，苯磺酸甲酯醇解，补偿效应本文研究了苯磺酸甲酯在ＣＨ＿３ＯＨ，Ｃ＿２Ｈ＿５ＯＨ，ｎ－Ｃ＿３Ｈ＿７ＯＨ和ｎ－Ｃ－４Ｈ＿９ＯＨ中的醇解反应速率随温度的变化情...The nucleophilic alcoholysis of methyl benzensulfonate in CH_3OH、C_2H_5OH、n-C_3H_7OH and n-C_4H_9OH have been studied kinetically. The activated energies, the exponential prefactorsaccording to Arrhenius'S equation, the activated enthalpics and the activated entropies according toTs theory have been obtained. Analysis of these data reveals that the difference among the activatedenergies is mainly due to the hydrogen bonding between alcohol molecules. The evident compensation interaction of the activated enthapies and activated entropies of these reactions has been discussed.
