Abstract

Ultrasound(50KHz) accelerated the reduction reaction of aromatic nitro group to aromatic amino group in high yield with mild condition using iron, hydrazine hydrate and activated carbon under room temperature and atmospheric pressure. The activated carbon has been used as a mixing material to highly active metals. However, aromatic nitro group does not reduce at all only with iron-hydrazine witliout adding activated carbon even under ultrasonic irradiation. We also discovered that the conversion yield from nitro group to amino group is directly proportional to the amount of activated carbon.

초음파(50KHz)가 상온 상압하에서 히드라진 철 활성탄을 이용한 방향족 니트로기를 방향족 아미노기로의 환원반응을 크게 가속시켜 3시간만에 100% 전환율을 얻을 수 있었다. 활성탄은 탈색이나 반응성이 큰 물질의 분말을 섞는데 사용되어 왔으나 히드라진 철을 이용한 방향족 니트로기의 환원반응에서는 활성탄 없이는 반응이 전혀 일어나지 않으며 활성탄의 증가에 따라 환원율이 높아지는 결과를 얻었다.
