合成气路线生产乙二醇技术进展

Research Progress in Synthesis of Ethylene Glycol by Way of Coal

介绍了合成气合成乙二醇的工艺发展情况,包括合成气直接合成法、甲醇甲醛合成法和草酸酯法等。着重介绍了合成气合成乙二醇的工艺和工艺进展情况,在比较不同工艺路线的同时,从现有的经济技术条件出发,提出了大力发展甲醇甲醛合成法和草酸酯法合成乙二醇的战略思路。

Recent progresses in the study on the conversion of syngas to ethylene glycol, including direct synthesis by syngas and indirect synthesis by methanol and formaldehyde or oxalate, are introduced. It is suggested that the routes using methanol and formaldehyde or oxalate as the intermediurns should be developed according to the recent economical and technological conditions.
