Description

톨루엔 디아민의 이성체 분리방법
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1-5도는 실시예 2-6에서 산출된 다른 지올라이트(Zeolite)흡착제와 탈착제를 사용하여 펄스방법으로 톨루엔 디아민의 이성질체의 분리를 나타내는 크로토마토 그래프의 기록이다.

Claims (10)

  1. 흡착상태에서 Ni, Ca, Ba, K 및 Na 그룹으로부터 선택된 양이온으로 치환된 X 타입 지올라이트 또는 Ca 및 Ni 양이온으로부터 선택되어 양이온으로 치환된 Y타입 지올라이트 또는 K 양이온으로부터 치환된 L타입 지올라이트를 합유한 흡착제로 상기의 혼합물을 접촉시켜 상기의 톨루엔 다아민 이성체중의 하나를 선택적으로 흡착하여, 혼합물의 나머지를 흡착제로부터 제거시킨 다음, 탈착 상태에서 저급 알코올 또는 아민을 함유한 탈착제로 흡착제를 제거시키는 것에 의해 흡착 톨루엔 디아민을 회수하여 2, 4-톨루엔 디아민 및 2, 6-톨루엔 디아민을 포함한 급송 혼합물을 분리하는 공정.
  2. 제1항에 있어서 상기의 흡착 및 탈착 조건이 약 20℃에서 200℃까지의 온도 범위를 가지며 액상을 유지하는데 충분한 압력을 포함한 것을 특징으로 하는 공정.
  3. 제1항에 있어서 상기의 공정이 그와 유사한 이동상(simulated moving bed) 흐름 시스템의로 특징 짓는 공정.
  4. 제1항에 있어서 상기의 공정이 정적상 시스템으로 특징짓는 공정.
  5. 제1항에 있어서 상기의 탈착제가 저급 알코올을 포함한 것을 특징으로 하는 공정.
  6. 제1항에 있어서 상기의 탈착제가 알킬아민을 포함한 것을 특징으로 하는 공정.
  7. 제6항에 있어서 상기의 탈착제가 부가적으로 톨루엔을 포함한 것을 특징으로 하는 공정.
  8. 제1항에 있어서 상기의 탈착제가 n-부틸아민 및 메탄올 그리고 에탄올을 구성하고 있는 그룹으로부터 선택된 것을 특징으로 하는 공정.
  9. 제8항에 있어서 상기의 탈착제가 부가적으로 에탄올을 포함한 것을 특징으로 하는 공정.
  10. 제1항에 있어서 상기의 흡착제가 Ba로 이온치환된 지올라이트 또는 K 로 치환된 L 지올라이트인 공정과 선택적으로 흡착된 톨루엔 디아민 이성체가 2, 6-톨루엔 다아민인 공정.
