三次样条法在醋酸甲酯催化水解动力学研究中的应用

在进行醋酸甲酯催化水解动力学的研究中 ,采用三次样条插值与微商法对实验数据进行了处理 ,处理结果与文献 1]所得结论一致 .与最小二乘法相比 ,该处理方法有其自身的优势 :无需对化工动力学微分方程进行求解 ;可直接获得反应速度随时间或浓度变化的规律 ;所得到的浓度—时间计算模型可以很好地表达反应全过程 .此数据处理方法为实验数据处理提供了新的途径

The application of cubic spline different quotient interpolation to kinetic study on the hydrolysis of methyl acetate

In the kinetics study on the hydrolysis of methyl acetate, the data were processed by cubic spline different quotient interpolation. Thus, the conclution from this method were consistent with the results in literature, and the method has a lot of advantage comparing with one-variable linear regression: the solution for the diferential equation of kinetics on chemical reaction mustn't be worked out, the reaction rate varying with the reaction time or concentration can be gained directly, calculation model of the reaction concentration-time can satisfy the whole reaction process. It provided a new way for chemical data processing.
