Abstract

The ionisation constants of N‐0‐tolyl‐p‐substituted benzohydroxamic acids have been determined in 10‐70% v/v dioxane‐water media at 25 and 35Β±0.1Β°C. The pK~a~'s in aqueous media (at 10% dioxane) have been obtained using the method of extrapolation and least squares. The pK~a~ values vary linearly with the mole fraction of dioxane. These constants are tested for the applicability of the Hammett equation.

The equilibrium constant for the keto-enol tautomerism of 3nitrobutan-2-one K T = [enol]/[ketone] has been measured in water as 4.57 Ο« 10 -3 (pK T = 2.34) by combining the rate constants for ketonisation of the enolate form and pK a of the ketone at 25 Β°C. The rates of ketonisation were measured by
