摘要
通过实验取得了甲醛和甲醇合成甲缩醛的反应参数;建立了其连续生产工艺的数学模型,利用ASPEN PLUS软件对甲醛和甲醇缩合生成甲缩醛进行了模拟,结果表明反应精馏连续生产甲缩醛的工艺是可行的,转化率高达99%,并得到含甲缩醛99%的产物,同时确定了进料板和反应区。
The experiment gains reaction parameters of methylal from formaldehyde and methanol , it also found a mathematical model for continuous production process .The synthesis of methylal using formaldehyde and methanol is simulated by ASPEN PLUS software. The results show that process produced methylal through reactive distillation and continuous production is feasible , in which convertion rate is promoted to 99 % ,and obtain production contained 99 % methylal ,feed and reaction tray are also determined.
