摘要
应用正交设计确定实验方案,分析了40～60℃对甲苯磺酸催化丁酸与乙醇反应合成丁酸乙酯时,反应温度、催化剂用量、丁酸与乙醇初始摩尔比对酯化反应的影响.根据实验所得的数据,进行非线性回归,得到了实验条件范围内该酯化反应的速率方程.
Catalyzed by toluene-p-sulfonic acid, the kinetics of the esterification of ethanol with n-butyric acid was studied. Using orthogonal experimental method, the influences of the usage of catalyst, the ratio of ethanol to n-butyric acid and temperature on the reaction rate were analyzed. According to the kinetic data, the kinetic equation was obtained using nonlinear regression.
