摘要:乙二醇在国民经济中有着极其重要的地位，广泛用于生产聚酯纤维、薄膜、容器瓶类等聚酯系列产品和汽车防冻剂，但国内乙二醇的产量一直无法满足国内市场的强劲需求。因此，本设计以乙二醇精制为中心和重点，经过严密的计算和论证，得到了肯定的结果。

关键词：乙二醇；环氧乙烷；水合法。

Abstract:Glycol in national economy plays an very important role, widely used in the production of polyester fiber, thin films, such as containers of polyester series products and automobile antifreeze domestic production of ethylene glycol, but have been unable to meet domestic strong market demand. Therefore, this design with ethylene glycol refined as the center and focus, with rigorous calculation and argument, got the positive results. Keywords: glycol; Epoxy ethane; Water legal.
