title: Ionic equilibria in neutral amphiprotic solvents; resolution of acid strength in tert-butyl alcohol.
abstract: The dissociation constants of several families of acids and their tetrabutylammonium salts, as well as the ternary-ion formation constants, in tert-butyl alcohol medium, were determined by potentiometric and conductometric methods. The comparison of the calculated pK values of the acids with those obtained in other amphiprotic media shows the better resolution of acid strength in tert-butyl alcohol. The different behaviour of acids of the same family, for two main series studied, phenols and mercaptopyrimidines, has been explained in terms of structure.
