【摘要】 研究了用强酸性阳离子交换树脂催化乳酸和乙醇酯化反应的动力学,通过对实验结果的分析,发现该反应正反应为二级反应,逆反应为零级反应,并由此推导出了反应动力学方程。同时还发现在温度较低时这一反应存在诱导期现象,并对这一现象进行了分析。更多还原

【Abstract】 The reactional kinetics of esterification is studied between lactic acidic and ethanol in the presence of acidic ion exchange resin catalyst.The conclusion is obtained by analyzing the experiment result,finding that the positive reaction is second order reaction,the reverse reaction is zero order reaction.The kinetic equation may be gained.The phenomenon of inducement period is also found when the temperature is lower,the phenomenon is also analysised in this work.更多还原
