摘　　要：通过生产工艺和物化性能的对比,阐述了草酸酯法乙二醇与乙烯法乙二醇二者的异同之处。生产工艺的差异导致所产乙二醇产品所含杂质不同,但均可得到质量指标符合国标GB/T4649-2008中优等品要求的产品。草酸酯法乙二醇可替代乙烯法用于PET生产。The similarities and differences of oxalic ester-based and ethylene-based ethylene glycol （EG） products were presented through the comparison of production processes and product properties. The difference of two production processes results in the impurity difference of EG products, however, both processes could obtain the high-class product which meets the requirements of the national standard GB/T4649-2008. Oxalic ester-based EG can be used for the production of PET instead of ethylene-based EG.
