본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음

Claims (1)

  1. 아닐린 용매속에 팔라듐 또는 팔라듐-백금 촉매를 침착시킨, 오일 흡수도가 100 이상인 친지성 탄소를 현탁시키고, 거의 무수의 조건하에 150 내지 250℃의 온도에서, 반응중에 형성된 아닐린과 물을 반응 생성물로부터 연속적으로 증발시키고, 반응 용액중의 니트로벤젠의 농도를 0.01중량% 이하로 유지시키면서 반응을 수행하고, 아연 화합물을 조촉매로서 반응계에 가하고, 일산화탄소를 1 내지 500ppm의 농도로 수소에 가하여 반응을 수행하여 수소로 니트로벤젠을 수소화 반응시킴을 특징으로 하는 아닐린 연속 제조방법.
