Abstract

$VO^{2+}-catalyzed oxidation of n-butylamine by hydrogen peroxide shows that the reaction is a first order in the concentration of n-butylamine, acid added, and VO^{2+}$ as catalyst, respectively. The reactions involve the initial formation of an imine intermediate, followed by hydrolysis to butyraldehyde and ammonia. It is suggested that the rate-determining step is a process dehydrogenation of n-butylammine.

<ㅆㄸㅌ>$VO^{2+} 촉매가 존재하는 수용매에서 과산화수소에 의한 n-부틸아민의 산화반응은 n-부틸아민, 산 및 촉매인 VO^{2+}$농도에 대해서 각각 일차의존성을 보여주었다. 이 산화반응은 처음에는 이민중간물질이 생성된 다음에 가수분해되어 부틸알데히드와 암모니아를 생성한다. 이 반응의 속도결정단계는 n-부틸아민의 탈수소화반응이 일어나 이민이 생성되는 과정임을 제시한다.
