P-아미노 페놀의 정제방법
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음

Claims (1)

  1. 내트로벤젠을 산성 매체내에서 촉매적 환원시켜 제조한 p-아미노페놀 수용액(여기에는 불순물로서 4,4´-디아미노디페닐에테르 및 아닐린이 존재함)을 염기로 중화시켜 수용액의 pH를 4.0내지 5.0으로 조절하고 생성된 수용액을 아닐린 및 톨루엔의 혼합물(4:1내지 1:4용적부)로된 유기용매로 추출함으로써 4,4´-디아미노디페닐에테르를 선택적으로 유기용매에 추출시켜 주로 p-아미노페놀을 함유한 수성상과 p-아미놀페놀, 4,4´-디아미노디페놀에테르 및 소량의 기타 아민 부산물을 함유한 유기 아닐린-톨루엔상을 얻은후, 수성상을 유기상으로 부터 분리시키고, 수성상으로 부터 순도가 개선된 p-아미노페놀을 회수함을 특징으로 하여 불순물이 함유된 p-아미노페놀을 정제하는 방법.
