Research progress of synthesis of 1,2-dimethoxyethan
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.
