Description

클로로포름, 메틸렌 클로라이드 및 클로로푸란으로 구성된 혼합물에서 아세트알데히드를 분리시키는 방법Method for separating acetaldehyde from a mixture consisting of chloroform, methylene chloride and chlorofuran

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

Claims (1)

동일 중량 내지 동일중량의 15배로 물을 첨가시킴으로써 알데히드 함유 수용액상과 클로로포름, 메틸렌 클로라이드 및 클로로푸란으로 구성된 액상을 생성시키며, 탑저수준이나 분리장치의 20%이하의 실제분리탑 높이에서 물을 연속적으로 도입하여 분리시킬 혼합물을 물 유입구수준에서 도입하여 클로로포름, 메틸렌 클로라이드 및 클로로푸란으로 구성된 액상이 탑 유출구에서 연속 또는 불연속적으로 추출되며 알데히드 함유 수용액상이 탑상부에서 연속적으로 추출되게 하고, 분리되는 혼합물이 2단계 처리공정에 의해 에틸렌과 공기에서 아세트 알데히드를 제조하는 것으로부터 얻어진 탑측부의 측부 유출물 임을 특징으로 하는 클로로포름, 메틸렌 클로라이드 및 클로로푸란으로 구성된 혼합물에서 아세트알데히드를 분리시키는 방법.By adding water in the same weight to 15 times the weight, water is produced in the form of aqueous solution containing aldehyde and liquid phase composed of chloroform, methylene chloride and chlorofuran, and water is continuously added at the bottom of the tower or at the actual separation tower height of 20% or less of the separator. The mixture to be introduced and separated is introduced at the water inlet level so that the liquid phase consisting of chloroform, methylene chloride and chlorofuran is continuously or discontinuously extracted at the tower outlet, and the aldehyde-containing aqueous phase is continuously extracted at the top of the column. A process for separating acetaldehyde from a mixture consisting of chloroform, methylene chloride and chlorofuran, characterized in that it is a side effluent from the top side obtained from the preparation of acetaldehyde in ethylene and air by a two step treatment process. * 참고사항 : 최초출원 내용에 의하여 공개하는 것임.* Note: The disclosure is based on the original application.
