甲基丙烯酸甲酯是制备丙烯酸树脂的重要原料，具有广泛的用途，甲基丙烯醛的分离是甲基丙烯酸甲酯生产的关键技术。本研究开发了共沸蒸馏法和离子液体（IL）绿色法分离MAL与BmimBF（4）。用白杨plus对这两个过程进行了模拟。模拟结果与中试装置的实验结果吻合较好。并对这两种工艺进行了经济性和绿色度分析。与共沸精馏工艺相比，IL绿色工艺具有经济优势和绿色度优势。(C)2010美国化学工程师学会AIChE J，57：2388-2396，2011
Separation of met hacrolein (MAL) is a critical technique for the production of methyl methacrylate, which is an important raw material for the preparation of acrylic resins applied in a variety of end-uses. In this work, an azeotropic distillation process and an ionic liquid (IL) green process were developed for the separation of MAL with BmimBF(4). The two processes were simulated with Aspen plus. The simulated results are in good agreement with the experimental results which were attained in a pilot plant. Also the economic and green degree analysis of these two processes was investigated. When compared with the azeotropic distillation process, the IL green process exhibits economic superiority and green degree superiority.
