摘　　要：运用Aspen Plus软件对异丁醛(IBD)氧化制甲基丙烯酸甲酯(MMA)的工艺流程进行了模拟与优化。模拟优化参数为:(1)IBD氧化制备甲基丙烯酸(MAA)工艺阶段:反应温度325℃左右、空速1500 h^(-1)、原料气n(O_(2))∶n(IBD)为(2.5~3.5)∶1、原料气中IBD含量应不超过5.0%;(2)MAA酯化制备MMA工艺阶段:理论塔板数为11、原料进料位置为第5块塔板、萃取剂进料位置为第4块塔板、回流比0.6。We simulated and optimized the preparation process of methyl methacrylate(MMA)via oxidation of isobutyraldehyde(IBD)by using Aspen Plus software.The parameters are simulated and optimized as follows:in the process stages of preparation of methylacrylic acid(MAA)from IBD,the reaction temperature is about 325℃,the airspeed is 1500 h^(-1),the molar ratio of O_(2) to IBD in feed gas is(2.5-3.5)∶1,and the IBD content in feed gas is no more than 5.0%;in the process stages of preparation of MMA from MAA,the theoretical tray number is 11,the feeding position of raw materials is in the fifth tray,the feeding position of extractant is in the fourth tray,and the reflux ratio is 0.6.
