摘要：

The oxidation of thioglycollic, thiolactic and thiomalic acids by tetraethylammonium chlorochromate (TEACC) is first order both In TEACC and thioacids. The reaction is catalysed by hydrogen ions. The hydrogen ion dependence has taking the form : k(obs) = a + b [H+]. The oxidation of thiolactic acid has been studied in nineteen different organic solvents. The solvent effect has been analysed by using Kamlet's and Swain's. multiparametric equations. A mechanism involving the formation of a thioester and its decomposition In slow step has been proposed.
