摘要
介绍了利用生产乙二醇时的副产二甘醇经催化环合生成1,4-二氧六环粗品,再经除过氧化物、除醛类杂质、除水等操作,生成含量99.5％以上高纯度产品的方法。
In this paper, the method of preparation of high purity 1,4-dioxane from diethylene glycol via ring-closure reaction, deperoxide, dealdehydes and dehydration was studied. Content of the 1,4-dioxane increased from 96. 7% to 99. 5%.
