工艺设计
设计说明:甲基丙烯酸甲酯(MMA)是合成有机玻璃及MBS树脂的单体。我国MMA的生产以丙酮腈醇法(ACH法)为主,合成路线复杂,工艺流程长,多步反应后产率低,成本高。该方法采用剧毒的氢氰酸为原料,产生大量难于处理的废酸,环境污染严重,因此开发新的MMA工艺路线很有必要。近年来,很多国家采用异丁烯为原料来生产MMA并已实现工业化。该方法生产绿化、经济效益高,推广应用后能获得较大的经济效益和社会效益。本文是对异丁烯制备MMA进行工艺设计。6718

A Process Design for 100,000 Tons Isobutane Conversion to Methyl Methacrylate by Two-Stage
1 / 29
Design notesMethyl methacrylate (MMA) is a monomer that is used to polymerize the organic glass and the MBS resin. MMA is produced by the method of acetone-cyanohydrin(ACH) mainly in our country. The synthetic route is complex, the technical line is long, and the yield is low with high cost aft
er many steps. Hydrocyanic acid (seriously poisonous) is used as raw material, the treatment of numerous waste acid is difficult . Furthermore, concentrated sulfuric acid consumed in this method corrodes equipments and pollutes the environment seriously. Considering all of these, it is greatly necessary to develop a new chemical technology of MMA. Recently, in many countries isobutyl is used as raw material to produce MMA and the method already is industrialized. This is the synthesis of Isobutene Conversion to Methyl Methacrylate by Two-Stage process design.
