合成气合成乙二醇的研究进展

Progress in Synthesis of Ethylene Glycol through Synthetic Gas

介绍了合成气合成乙二醇的工艺进展情况,包括合成气直接合成法、甲醇甲醛合成法和草酸酯法等。在比较不同工艺路线的同时,从现有的经济技术条件出发,并对各种方法的工艺技术特点进行了评述,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。

In this paper, progresses in the study on the conversion of synthetic gas to ethylene glycol , including direct synthesis by synthetic gas and indirect synthesis by methanol and formaldehyde or oxalate, were introduced. And the advantages and disadvantages of above processes were reviewed. It was suggested that the routes using methanol and formaldehyde or oxalate as the intermediums should be developed according to the recent economical and technological conditions.
