The constants for ion-pair formation with 2,4-dinitrophenol in benzene (KB), the pKa values in water, of thirty-three amines have been measured.According to the class of amine, two different situations can be observed: for primary amines and secundery cyclic amines, the effects of structural variations on basicity are higher in water than in benzene; on the other hand, for tertiary amines these effects are similar in the two solvents.KB Values of primary amines give a good correlation with ? *.The Tatf and Hancock equation allows a unifying treatment of KB values of the various classes of amines.
