摘　　要：研究以丙酮为原料液相法合成异佛尔酮的液相缩合反应动力学．考察Na0H为催化剂，催化剂用量、压力、温度、反应时间对反应的影响．结果表明，反应温度215-225℃、丙酮与水质量比3：1、0．13mol NaOH、压力3．8～4．5MPa为最优反应条件，其表观活化能5L31kJ／mol，对丙酮消耗速率的动力学方程-rA=0．953×10^3e^-1310/RT CA，经统计检验，所得反应速率方程是可信的，可用于反应器的模拟计算．The liquid-phase condensation reaction kinetics of isophorone synthesis was investigated by using acetone as raw materials. The influence of catalyst concentration,pressure, temperature and other factors on the reaction was investigated with NaOH as catalyst. It was found that the optimal reaction condition was as follows： the reaction temperature 215-225 ℃, mass ratio of acetone to water 3： 1, 0. 13 mol NaOH, and pressure 3.8-4. 5 MPa. Its apparent activation energy was 51.31 kJ/mol and reaction kinetic equation of acetone consumption was presented as follows： -rA=0.953×10^3e^-1310/RT CA being statistically verified as credible, and practicable for simulative evaluation of reactors.
