Abstract

Autoxidation kinetics of potassium O-butyl dithio-carbonate catalyzed by cobalt(II) tetrasulfophthalocyanine has been studied polarographically. The reaction follows two parallel pathways of zero and first order with respect to dioxygen, each being a “Michaelis” function of the substrate concentration. On the basic of data obtained and those reported previously for cysteine autoxidation, a general reaction mechanism is suggested.

Abstract

Полярографически изучена кинетика аутоокисления O-бутилдитиокарбоната калия, катализируемого тетрасульфофтало-цианином кобальта(II). Реакция идет по двум параллельным маршрутам, нулевого и первого порядков по кислороду, каждый из которых имеет “михаэлисовскую” зависимость от концентрации субстрата. На основании этих, а также ранее предложенных для аутоокисления цистеина, данных предложен общий механизм реакции.
