摘要
二甘醇(DEG)是环氧乙烷用水合法生产乙二酵(EG)的副产物,随着我国乙二醇工业的迅速发展二甘醇产量不断增加,充分利用二甘醇资源开发下游产品、拓展二甘醇的用途越来越受到重视。综述了国内二甘醇的综合利用进展,介绍了二甘醇的直接利用途径和二甘醇合成吗啉、二甘醇醚、二甘醇酯、1,4-二氧六环、二甘酸和二甘醇胺等精细化学品的利用情况。
As the byproduct of ethylene glycol （EG） produced by hydration of ethylene oxidation, diethylene glycol （DEG） was increased in output with the rapid devolopment of ethylene glycol industry in China. Thus, the development of derivative products of DEG and the new uses of DEG got more and more attention. The advances in the comprehensive utili- zation of DEG in China was introduced, and the application of DEG＇ s downstream, such as morpholine, diethylene glycol ethers, diethylene glycol esters, 1,4 - dioxane, diglycolic acid, diethylene glycol amine etc. were described in this paper.
