구리(Ⅱ)-아민류 착물에 의한 l-ascorbic acid의 산화반응속도와 메카니즘
The rates for the oxidation reaction of l-ascorbic acid by Cu(Ⅱ)-polyamine complexes were measured by Onish's method at the pH 4.6. The oxidation process of l-ascorbic acid is proposed to occur by the inner-sphere mechanism that involves the formation of a Cu(Ⅱ)-ascorbic acid complex and electr...

Zusammenfassung: | The rates for the oxidation reaction of l-ascorbic acid by Cu(Ⅱ)-polyamine complexes were measured by Onish's method at the pH 4.6. The oxidation process of l-ascorbic acid is proposed to occur by the inner-sphere mechanism that involves the formation of a Cu(Ⅱ)-ascorbic acid complex and electron transfer at the rate-determining step. 구리(II)-아민류 착물에 의한 l-ascorbic acid의 산화반응속도를 pH 4.6에서 Onishi 방법으로 측정하였다. 이 반응의 메커니즘은 l-ascorbic acid가 구리(II) 착물에 배위된 다음 속도결정단계에서, 전자이동이 일어나는 내부권 메커니즘에 따라 반응이 진행됨을 알았다. |
