Analysis of the isotope effect in the hydrogen exchange reaction between pyridinium chloride and hydrogen chloride
Hydrogen isotope exchange between pyridinium chloride and gaseous hydrogen chloride has been studied both experimentally and theoretically over the temperature range of 273 to 353 K. The experimental fractionation factor obtained shows some dependence on the composition of the substrates. This phenomenon can be accounted for by specific interactions in pyridinium chloride + hydrogen chloride system. The calculated fractionation factor in harmonic approximation and within the framework of quantum statistical theory of isotope effects agrees satisfactorily with the experimental results in these cases when well-defined species of Py(HCl)/sub 2/ were formed and the nature of the interactions were well enough known. In other cases some interaction models have been proposed and briefly discussed.
