环氧乙烷(EO)是乙烯工业衍生物中仅次于聚乙烯和聚氯乙烯的重要有机化工产品,主要用于生产聚酯纤维、聚酯树脂和汽车用防冻剂的原料单乙二醇(MEG)以及二乙二醇(DEG)、三乙二醇(TEG)和聚乙二醇(PEG)等多元醇类。此外,环氧乙烷还可用于生产乙氧基化合物、乙醇胺、乙二醇醚以及聚醚多 Ethylene oxide (EO) is an important organic chemical product second only to polyethylene and polyvinyl chloride in industrial derivatives of ethylene. It is mainly used in the production of raw materials of polyester glycol, polyester resin and automobile antifreeze mono-ethylene glycol (MEG) and polyhydric alcohols such as diethylene glycol (DEG), triethylene glycol (TEG) and polyethylene glycol (PEG). In addition, ethylene oxide can also be used to produce ethoxylates, ethanolamines, glycol ethers and polyether
