Kinetics of Oxidation of Isobutylene with Thallium(III)lon

Abstract

The kinetics of oxidation of isobutylen, e with thallium(III)ion, were studied, because its reaction mechanism was of interest. The reaction was carried out in a stirred vessel with a flat gasliquid interface in a diffusion controlled region, because the reaction proceeded too rapid to be observed by ordinary kinetic method.
The observed absorption rates of isobutylene were tested by way of trial that the reaction to be any of (m n)th-order irreversible ones, and we found that it was of the first-order with respect to both isobutylene and thallium(III)ion.
The obsLerved absorption rates of isobutylene were further analyzed based on the assumption that the reaction was consecutive one consisting of complex formation, complex rearrangement and a complex hydrolysis, and we found that rr complex forming rea tion was irreversible,
