用高效液相色谱法研究乙酸乙酯皂化反应动力学 THE KINETIC RESEARCH OF SAPONIFICATION OF ETHYL ACETATE WITH HPLC 周卓媛 Zhou Zhuoyuan Wang Cunxin Qu Songsheng Zhao Xin 1 2 first-author 汪存信 1 2 屈松生 1 2 赵昕 1 2 武汉大学化学系 武汉大学化学系 Department of Chemistry, Wuhan University Department of Chemistry, Wuhan University 北京联合大学化学工程学院 北京联合大学化学工程学院 用HPLC测定了乙酸乙酯反应反应动力学参数。通过色谱图给出的数据求得了反应的速率常数和活化能。实验测得在298.2K时乙酸乙酯皂化反应的速率常数为0.111mol -1 ·dm 3 ·s -1 ,活化能为46.7kJ·mol -1 。 The Kinetic parameters of saponification of ethyl acetate have been measured with HPLC. The concentration of reactant was obtained by means of peak area and height of the chromatographic figure. Then the rate cons-tant and the energy of activation were obtained further. The average rate constant at 298.2K is 0.111mol -1 .dm 3 .s -1 and the energy of activation is 46.7kJ.mo1 -1 . 乙酸乙酯 皂化反应 动力学 HPLC Ethyl acetate Saponification Kinetic HPLC 1989-03-01 2021-04-01 3
