By means of water as an extractant, the two‐feed and three‐feed reactive distillation production processes of methylal are synthesized and analyzed. The effects of water on the methylal reactive distillation (RD) production is investigated. Thermally coupled two‐feed and three‐feed reactive dividing‐wall columns are proposed and analyzed. The two‐feed and three‐feed RD processes are compared. The three‐feed thermally coupled reactive dividing‐wall column (DWC) exhibits an outstanding ability of energy and cost savings. Results from this work could be helpful for further development and application of RD or reactive DWC in methylal production.

反应性分馏塔蒸馏法用于甲基生产的合成与分析

以水为萃取剂，合成并分析了甲醇的两次进料和三次进料反应蒸馏生产工艺。研究了水对甲基反应蒸馏（RD）生产的影响。提出并分析了热耦合两进料和三进料反应性隔墙塔。比较了两次进料和三次进料的RD过程。三进料热耦合反应式分隔壁塔（DWC）具有出色的能源节约和成本节约能力。这项工作的结果可能有助于进一步开发RD或反应性DWC在甲基醛生产中的应用。
