乙二醇生产新工艺

New Processes for Producing Glycol

简述了乙二醇现有生产的工艺及其缺点，介绍了作者开发的联产化工原料碳酸二甲酯的乙二醇生产新工艺及以二氧化碳为载体的水解法乙二醇生产新工艺，与原工艺相比可节约蒸汽 57％、节约冷却水 50％、节约电 35％、提高收率 10％。

Processes for producing glycol such as the coproducing dimethyl carbonate,an environmentally benign green chemical product,process as well as the hydrolyzing ethylene carbonate process were developed.The results have shown an energy saving of more than 50％ and a yield increasing about 10％。
