Abstract

쿠멘 하이드로퍼옥사이드의 산분해생성물로 부터 얻어지고α-메틸스티렌 함량이 15중량%이하인 조페놀을 비표면적이 80- 400㎡/g 범위이고 하메트의 산도함수(Ho)에 의한 산강도가 3Ho6. 8인 산성r-알루미나로 접촉처리하여 조페놀증에 함유되어 있는 지방족 및 방향족 카보닐 화합물들을 조페놀중에 함유되어 있는α-메틸렌스티렌이 디머를 실질적으로 형성하지 않고 고비등화합물들로 변환한후에 증류에 의해서 페놀과 그와같이 형성된 고비등 화합물들을 분리시키는 고순도 페놀의 제조방법.

(2) 단계(1)에서 얻은 접촉처리생성물을 증류하여 페놀을 회수하는 단계로 구성된, 고순도페놀의 제조방법.
  2. 제1항에 있어서. 상기 조페놀을 150-300℃의 온도범위에서 접촉처리하는 것을 특징으로 하는 고순도 페놀의 제조방법.
  3. 제1항에 있어서, 상기 조페놀을 1~50분 동안 접촉처리하는 것을 특징으로 하는 고순도 페놀의 제조방법.
  4. 제1항에 있어서, 상기 산성r-알루미나의 산도함수(Ho)에 의한 산강도가 3Ho6. 8인 것을 특징으로 하는 고순도 페놀의 제조방법.
  5. 제1항에 있어서, 상기 산성r-알루미나가 150~300㎡/g범위의 비표면적을 갖는 것을 특징으로 하는 고순도페놀의 제조방법.
  6. 제1항에 있어서, 상기 조페놀을 기상으로 산성 r-알루미나로 접촉처리하는 것을 특징으로 하는 고순도 페놀의 제조방법.
  7. 제1항에 있어서, 상기 조페놀을 액상으로 산성 r-알루미나로 접촉처리하는 것을 특징으로 하는 고순도 페놀의 제조방법.
  8. 제1항에 있어서, 상기 접촉처리 생성물을 스팀증류 또는 유기용제 추출증류에 의해서 회수하는 것을 특징으로하는 고순도 페놀의 제조방법.
