摘　　要：介绍了氧烃化、乙烯加成、氢解、氯化物分子间的消除、甲醚的偶联等反应,综述了生产与合成乙二醇二甲醚的方法,包括其工艺流程、催化剂和反应条件,并重点介绍了Williamson合成法以及由环氧化合物开环与二甲醚的插入反应合成乙二醇二甲醚的合成工艺路线的研究进展,认为由碳酸二甲酯与乙二醇单甲醚以及甲醚与环氧乙烷制备乙二醇二甲醚,具有重大应用前景。The production and synthesis of 1,2-dimethoxyethane are reviewed from several methods such as O-alkylation, addition of ethylene, hydrogenolysis, elimination between chlorides, Cadiot-Chodkiewicz of dimethyl ether, etc. The discussions are also made on processes, catalysts and reaction conditions. The methods of Williamson synthesis method and the ring opening of ethylene oxide and insertion of dimethyl ether are also reviewed. The development status of preparing 1,2-dimethoxyethane from methoxyethane and dimethyl carbonate or dimethyl ether and epoxyethane is presented.
