摘要
本文对苯酚和过量丙烯烷基化反应为多步连串反应的假设,建立了一组拟一级反应动力学模型,并确定了在不同温度下各反应步骤的速度常数和相应的活化能。该模型各组份的预测值和实验结果符合较好。
This paper supposes that the alkylations of phenol with on excess of pro-pylene are consecutive reactions involving many steps, there from a kinetic model of several pseudo first order reactions was established. These reaction rate constants and their activation energies were determined at different temperatures. Prediction of composition of the products by this model was shown in good agreement with the experimental data.
