Claims (6)

  1. 주기율표(Ib)족에서 선택된 1가지 이상의 원소를 함유하는 촉매 존재하에서 아닐린과 디올을 반응시켜서 인돌을 함유하는 반응 혼합물을 얻고, 이 반응 혼합물로 부터 반응하지 않은 아닐린을 분리, 회수하여 이 회수된 아닐린을 이 반응에 재사용하는 것으로 구성되는 인돌 제조 방법에 있어서, 이 아닐린이 하기 일반식(Ⅰ)의 화합물 2중량% 이하, 그리고 하기 일반식(Ⅱ)의 화합물 0.2중량% 이하를 함유하는 것을 특징으로 하는 방법.
  3. (상기 일반식들에서, R1은 수소원자, 할로겐원자, 알킬기, 히드록시기, 알콕시기 또는 니트로기이고, R2및 R3은 각각 수소원자, 알킬기 또는 치환된 알킬기이며, R1', R2' 및 R3'는 각각 R1', R2' 및 R3'와 동일함).
  4. 제1항에 있어서, 회수된 아닐린이 반응혼합물 또는 이 반응혼합물로 부터 분리한 아닐린을 열처리한 다음에 증류시켜서 얻은 아닐린인 방법.
  5. 제2항에 있어서, 열처리를 100°∼350℃에서 실시하는 방법.
  6. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
