摘要
Abstract
MGN(2-methylglutaronitrile)is the main byproduct in the industrial production of adiponitrile.The catalytic hydrogenation of MGN to high-value MPDA(2-methylpentanediamine)is of great significance.It improves the economic benefits of the nylon industry and aids in achieving green chemical production.However,severe cyclization side reactions occur during this process.This leads to the formation of 3-MP(3-methylpiperidine),a byproduct that is difficult to separate.Additionally,the complex reaction kinetics and separation processes limit its industrial application.The process routes for the hydrogenation of MGN to prepare MPDA in recent years were reviewed.The strategies for catalyst design were highlighted.Specifically,the regulation mechanisms for inhibiting cyclization side reactions were discussed.The research progress on reaction kinetic models and product separation technologies was also systematically summarized.Finally,future development directions were proposed,including the development of high-selectivity catalysts,the optimization of continuous flow reaction processes,and the construction of efficient separation systems.关键词
