Abstract
A kinetic method for the determination of the species of “CO 2”, i.e. CO 2 or HCO 3 − actively fixed in car☐ylation reactions, has appeared recently in the literature. This method is predicated upon the fact that the hydration of CO 2 requires more than 60 seconds to reach equilibrium at temperatures below 15 °C. Although the method is relatively straight-forward in technique and interpretation, it is quite time consuming if the theoretical results are calculated by hand. In the present work the necessary differential system has been solved employing digital computer techniques ‡ and the theoretically expected results have been calculated over a wide range of temperatures and hydrogen ion concentrations. It was shown that, in as far as possible, the method is most advantageously used at temperatures close to 5 °C and hydrogen ion concentrations close to 10 −8.
