甲基丙烯酸甲酯生产技术路线及经济性评价

阐述了甲基丙烯酸甲酯（MMA）现行的4种生产技术路线,即丙酮氰醇法、异丁烯法、乙烯法和改进丙酮氰醇法,评价了上述方法的经济性,认为乙烯法不合国情,异丁烯法随着原油价格攀升已无优势,而丙酮氰醇法仍将是我国新建装置的首选方法,改进丙酮氰醇法对氢氰酸资源匮乏但蒸汽富余的企业可优先考虑。

Evaluation of MMA production technologies and their economy

Four kinds of current MMA production processes were introduced in this paper,which is acetone cyanohydrin process,isobutylene process,ethylene process and improved acetone cyanohydrin process.The economy of these four processes was also evaluated.Based on relevant studies,the ethylene process is considered not to conform to the condition of our country.With soaring crude oil prices,the isobutylene process has lost its advantage.Acetone cyanohydrin process will still be the first choice for new plants in China.And the improved acetone cyanohydrin process can be considered by the companies which have no hydrocyanic acid source but have sufficient steam.
