摘　　要：油酸甲酯与乙烯复分解反应是一类特殊的烯烃复分解反应,经过交叉复分解反应获得1-癸烯和9-癸烯酸甲酯两种端烯中间体,同时存在竞争性反应生成9-十八烯和9-十八烯-1,18-二甲酯。催化剂的选择对该反应的速率和选择性起着决定作用,随着高效、稳定的商业化钌基催化剂问世,逐渐拓展了该反应的工业化应用范围,但对该反应的研究目前仍然存在工艺条件不够完善、产物分布宽、均相催化剂昂贵且回收困难、非均相催化剂负载活性差等问题。本文详细阐述了油酸甲酯与乙烯复分解反应的机理,以催化剂的发展为轴线,从工艺条件、催化剂种类、产物工业应用等方面介绍了该反应的研究历程;以油酸甲酯转化率、产物产率和选择性、催化剂周转数(TON)值为基准,系统评估了该反应的研究进展。同时建议在今后探索中,除了对催化剂进行开发以外,还应结合实际条件对整个反应体系进行优化,实现反应、检测和分离一体化。The double decomposition reaction of methyl oleate and ethylene is a special kind of olefin double decomposition reaction.Two end-ene intermediates,1-decene and 9-decene methyl ester,are obtained through the cross double decomposition products.At the same time,9-octadecene and dimethyl-9-octadecene-1,18-diate,are produced through competitive reactions.The selection of catalysts plays a decisive role in the rate and selectivity of this reaction.With the emergence of highly efficient and stable commercial ruthenium catalysts,the industrial application range of this reaction is gradually expanded.However,there are still some problems in the research of this reaction,such as incomplete process conditions,wide product distribution,expensive and difficult recovery of homogeneous catalysts,and poor activity of heterogeneous catalysts.In this paper,the mechanism of the double decomposition reaction between methyl oleate and ethylene is described in detail.With the development of catalysts as the axis,the research process of the reaction is introduced from the aspects of process conditions,types of catalysts and industrial application of products.The research progress of this reaction was systematically evaluated based on the conversion rate of methyl oleate,product yield and selectivity,and catalyst turnover number(TON).At the same time,it is suggested that in the future exploration,in addition to the development of catalyst,the whole reaction system should be optimized according to the actual conditions,so as to realize the integration of reaction,detection and separation.
