Abstract
본 발명은 과증발시켜 트리옥산, 물 및 포름알데히드의 혼합물로부터 물을 추출하고, 정류시켜 물이 감손된 혼합물(보유액)을 트리옥산과 트리옥산, 물 및 포름알데히드의 공비 혼합물로 분리시킴을 특징으로 하는 트리옥산의 분리 방법에 관한 것이다.
Description
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도는 본 발명의 실시양태의 실례를 도시한 것이다.
Claims (2)
- 과증발시켜 혼합물로부터 물을 추출하고, 정류시켜 물이 감손된 혼합물(보유액)을 트리옥산과 트리옥산, 물 및 포름알데히드의 공비 혼합물로 분리시킴을 특징으로 하여, 본질적으로 트리옥산, 물 및 포름알데히드로 이루어진 수성 혼합물로부터 트리옥산을 분리하는 방법.
- 제1항에 있어서, 과증발이 폴리비닐 알콜의 막을 사용하여 70내지 120℃의 온도 및 보유액 측에서 1 내지 3bar이고 투과액 측에서 30내지 150mbar인 압력에서 수행되는 방법.※참고사항:최초출원 내용에 의하여 공개하는 것임.
