Abstract
본 발명은 디옥산과 물의 혼합물에서 물을 제거하여 순수한 디옥산을 얻는 방법에 관한 것이다.The present invention relates to a process for removing water in a mixture of dioxane and water to obtain pure dioxane.
구체적으로 설명하면, 함수 디옥산을 정제하는 방법에 있어 디옥산보다 용이하게 물과 공비점을 형성하는 유기용매를 사용하여 공비증류법으로 디옥산과 물을 분리하는 방법으로서 공비증류되어 나온 유기용매는 물과 쉽게 분리 · 회수할 수 있어 재사용도 가능하다.Specifically, in the method of purifying hydrous dioxane, an organic solvent that has been azeotropically distilled as a method of separating dioxane and water by azeotropic distillation using an organic solvent which forms an azeotropic point with water more easily than dioxane is used. It can be easily separated and recovered from water for reuse.
