摘要
采用以三氯化钌为主的催化体系,在高压釜中采用虹吸式涡轮搅拌器消除乙烯在气液两相中的传递因素对反应带来的影响,研究了以甲酸甲酯为原料,通过乙烯氢酯基化反应合成丙酸甲酯的催化反应动力学。探讨了该反应的机理,得到)(β-1)],反应速率常数k1=0 0668mol/(s·L),反应活化能CA/(1-1/β)][1-(CA/CA0反应的动力学数学模型为rp=[k1CM0E=81 363kJ/mol。
The kinetics about hydroesterification of ethylene with methyl formate in RuCl_3 catalyst system was studied. The effect of mass transfer on the reaction was eliminated through using suction turbine impeller. The reaction mechanism was discussed and the kinetic equation was deduced as r_p=[k_1C_(M_0)C_A/(1-1/β)][1-(C_A/C_(A_0))^((β-1))]. Rate constant (k_1) and active energy(E) obtained from the experiments are 0.0668mol/(s·L) and 81.363 kJ/mol, respectively.
