摘要
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 investigatedThe experiment results show that the general reaction equation is: -dpCO/dt=k··pCO· Within all experiment confine, the rate of CO is one progression and the activation energy is 6763 kJ/mol
