아릴 알코올을 함유하는 아세토니트릴을 둘의 존재하에 정류탑에서 추출 증류하여 탑의 정상부에서 소량의 물과 함께 하세토니트릴을 유출(留出)시켜 탑의 밑부분으로부터 아릴 알코올을 몰의 및 소랑의 아세토니트릴과 함께 혼합물로서 농축분리하는 것을 특징으로 하는 정제 아세토니트릴의 회수방법.Acetonitrile containing aryl alcohol was extracted and distilled in a rectifying column in the presence of two, and the acetonitrile was discharged along with a small amount of water from the top of the column to distill the aryl alcohol from the bottom of the column. A method for recovering purified acetonitrile, characterized in that it is concentrated and separated as a mixture with acetonitrile. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: Disclosure is based on the original application.
