| Abstract: | The kinetics of oxidation of methionine (MT) by hexamethylenetetramine-bromine (HABR) has been studied in acetic acid. The reaction leads to the formation of the corresponding sulphoxide. The reaction is first order in HABR. Michaelis-Menten type kinetics has been observed with respect to the methionine. The formation constants of the intermediate complex and the rate constants from its decomposition have been evaluated at different temperatures. The thermodynamic and activation parameters have also been evaluated. The addition of hexamine (HXA) has no effect on the rate. A mechanism involving the formation of a halogenosulphonium cation in the slow step has been proposed. |
