In this paper, the two-step method of isobutene production of methyl acrylic, the process is divided into two sections, the first complete the synthesis of methyl acrylic. Raw material isobutene and auxiliary raw materials have passed methyl acrylic synthesis reactor, isobutene is now the presence of catalyst conditions are oxidized, the process of the gas generated by the rapid cold spray tower, dewatering tower and exhaust tower. The top of the exhaust tower is a very small amount of unresponsive isobutene, nitrogen and oxygen, as well as a small fraction of the gas impurities generated by the intermediate process, all of which are processed into the torch system.
