摘要：研究了甲醇与环戊烯合成环戊基甲醚（CPME）的宏观反应动力学。环戊烯与甲醇摩尔比为1∶1,温度区间为115-130℃,采用离子交换树脂催化剂,反应在固定床反应器内发生,在液相条件下得到了相应的动力学数据。结果表明,甲醇优先紧紧地吸附在催化剂的活性位上,环戊烯吸附在相同的催化剂活性位上参与反应,反应呈现明显的一级反应的特征。采用非线性曲线拟合方法处理实验数据,建立了环戊烯醚化反应动力学方程。用动力学模型求得的计算值与实验值的相对误差均在5%以内,说明所建动力学模型能较好的描述环戊烯醚化反应,具有良好的外推性。
The kinetics of synthesis cyclopentyl methyl ether（ CPME） using methanol and cyclopentene was studied. The molar ratio of methanol to cyclopentene is 1∶ 1 and the experimental temperature ranged from 115 - 130 ℃. The rate data was obtained in a fixed-bed reactor with ion exchange catalyst. Result showed that methanol adsorbed on the active sites strongly,the cyclopentene adsorbed on the same active sites,and the reaction follows an apparent first-order behavior. The nonlinear curve fitting method was adopted to deal the experimental data and the kinetic equation was established. Compared the calculated values with the experimental values,the relative error all less than 5%. This result showed that the equation could well describe the etherification reaction and had a favorable extrapolation.
