Progress in synthesis of ethylene glycol through C1 chemical industry routes

Abstract

Ethylene glycol (EG) is an important industrial chemicals. It has attracted attention because it can be used to synthesize polyester resins and fibers. C 1 chemical industry routes have been explored for EG synthesis from syngas and coal as starting materials. It is suggested that such routes are more promising methods for EG synthesis than the use of petroleum is. The pertinent literature on EG synthesis through C 1 chemical industry routes are summarized. The methods include direct synthesis from syngas, carbonylation of formaldehyde, CO coupling reactions, hydroformylation of formaldehyde, and condensation of formaldehyde. 乙二醇(EG)是一种重要的化工原料, 主要用来生产新型聚酯纤维. 近年来由于我国聚酯产业发展迅速, 极大的推动了对乙二醇的需求. 碳一化工路线以资源丰富/价格便宜的天然气或煤为原料合成乙二醇, 有着诱人的工业化前景. 综述了以合成气为原料合成乙二醇的研究进展, 包括合成气直接合成法/甲醛羰化法/CO偶联法/甲醛氢甲酰化法以及甲醛缩合法等. Ethylene glycol (EG) is an important industrial chemicals and especially it could be used to synthesize polyester resins and fibers. The pertinent literatures on EG synthesis through C 1 chemical industry routes are summarized.
