Matlab在气相反应动力学实验数据中的应用

Application of Matlabin Experimental Data of Gas Reaction Dynamics

基于实验室自行搭建的流动管装置,用于气相反应动力学反应速率常数的测量。选用异戊酸叶醇酯与O_(3)反应体系,将Matlab软件编写程序用于异戊酸叶醇酯与O_(3)的气相反应动力学实验数据处理与绘图,根据最小二乘线性拟合得到反应速率常数为1.99×10^(-16)cm^(3)·molecule^(-1)·s^(-1),所得结果准确度高,避免了传统数据处理方法所带来的人为误差,具有方便、快速与直观等优点,可以补充和改进物理化学实验的教学。

The rate constant of gas reaction kinetics was measured based on a flow tube reactor built by the laboratory.The reaction system of cis-3-hexenyl 3-methylbutanoate and O_(3)was selected.The Matlab software was programmed for the experimental data processing and drawing of the gas reaction kinetics of cis-3-hexenyl 3-methylbutanoatewith O_(3).According to the least square linear fitting,the reaction rate constant was 1.99×10^(-16)cm^(3)·molecule^(-1)·s^(-1).The obtained results were of high accuracy,avoiding the human error caused by the traditional data processing methods.It was convenient,fast and intuitive,and can supplement and improve the teaching of Physical Chemistry experiment.
