Abstract:
A mechanism of the dehydration of 2-propanol and of the back reaction of the hydration of propylene in supercritical water was suggested; the mechanism corresponded to that of acid catalysis in solutions. The reaction rates in both directions were shown to be directly proportional to the concentration of the corresponding reagents and the H3O+ ions, which played the role of a homogeneous catalyst. It was also shown that a sharp increase in the concentration of H3O+ caused by increasing the density (pressure) unambiguously correlated with changes in the experimental rate constants for the pseudo-first-order reactions depending on the parameters specified above. The density-independent (pressure-independent) rate constants for bimolecular reactions were determined.
