A methodology using laboratory-scale autoclave reactor data and industrial process plant data is proposed to develop and validate the kinetics of controlled ethoxylation of mono-methyl amine (MMA) solution. Initially, the ethoxylation of mono-methyl amine solution was carried out using an autoclave reactor under isothermal conditions, and the rate of products: mono-methyl ethanolamine (MMEA), methyl-di-ethanol
提出了一种使用实验室规模的高压釜反应器数据和工业加工厂数据的方法来开发和验证单甲胺 (MMA) 溶液的受控乙氧基化动力学。最初,单甲胺溶液的乙氧基化是在等温条件下使用高压釜反应器进行的,产物的比例为:单甲基乙醇胺(MMEA)、甲基二乙醇胺(MDEA)和甲基乙二醇醚。 -二乙醇胺 (MDEA-P) 成立。然后,使用动力学模型参数的变化进行 Aspen Plus 过程模拟器灵敏度分析,以模拟真实工厂的产品分布。最后,通过比较通过高压釜反应器实验和基于模拟的真实工厂敏感性分析从经典动力学模型获得的活化能,验证了胺-乙氧基化反应动力学。从结果来看,对于 MMEA 形成,E a = 19.46 kcal/mol 和A = 6.02*10 8 ,对于 MDEA 形成, E a = 4.2 kcal/mol 和A = 21.12,对于 MDEA-P 形成, E a = 9.46 kcal/mol
