Abstract

Rates of the decomposition of hydrogen peroxide by copper(Ⅱ)-Schiff base complexes were measured at various concentrations of hydrogen peroxide. Decomposition rates of hydrogen peroxide increased with increasing pH for CuⅡBSDT and CuⅡBSTP but then decreased with the same variation of the pH for CuⅡBSTT. A possible mechanism in accord with experimental results was proposed. The mechanism involves the deprotonation of copper(Ⅱ)-Schiff base complexes of hydrogen peroxide, followed by the formation of peroxo complexes at the rate-determining step.

시프 염기 구리(II) 착물에 의한 과산화수소 분해속도를 측정하였다. 과산화수소와 구리(II)-시프염기 착물의 반응속도는 $Cu^{II}BSDT$ 및 $Cu^{II}BSTP$인 경우 pH에 따라 증가하였으나 $Cu^{II}BSTT$의 경우 증가하였다가 감소하였다. 이 반응의 메카니즘은 과산화수소의 시프염기 구리(II) 착물의 탈양성자를 거친 다음에 속도결정단계에서 퍼옥소 구리착물이 생성되는 반응과정과 일치한다.
