CO、甲醇液相羰化合成甲酸甲酯的动力学研究

Kinetic Study on Synthesis of Methyl Formate by Methanol Carbonylation

在釜式反应器中进行了CO与甲醇羰基化合成甲酸甲酯的动力学研究,在一定反应温度下,恒定进料压力、甲醇浓度(c(MeOH))、催化剂浓度(c(Cat)),考察了反应进程中CO分压(pCO)的变化。结果表明,甲醇钠催化下,甲醇羰化反应速率k在60～90℃温度范围内,对CO为一级,反应活化能Ea=67 63kJ/mol,反应动力学方程为:-dpCO/dt=kc(Cat)pCOc(MeOH)。

The kinetics about synthesis reaction of methyl formate from carbon monoxide and methanol was studied Fixing initial reaction pressure and the content of catalyst and methanol, the change of the pressure of carbon monoxide with different temperature during reaction had been investigatedThe experiment results show that the general reaction equation is: -dpCO/dt=k··pCO· Within all experiment confine, the rate of CO is one progression and the activation energy is 6763 kJ/mol 
