Kańska, R. Kański] The kinetic behavior of deuteriation of benzoic acid with D2O acidified with HCl in the presence of homogeneous K2PtCl4 catalyst has been investigated in the 100-130°C temperature interval. The quasiunimolecular H/D rate constants at 100 and 130°C corresponding to an exchange process in ortho positions of the substituted benzene ring hydrogens were determined by1H NMR integration signal. These same constants for meta and para positions have been deduced by analysis of the composite1H NMR signal, and the Arrhenius activation energies for these exchange reactions were estimated.
