Abstract
The Hammett acidity function concept has been used to determine simultaneously the pKavalues of 24 substituted anilines and diphenylamines and the H−values of various solvent systems. The following solvent systems were examined (the most basic H−value obtained for each is shown in parentheses): water containing benzyltrimethylammonium hydroxide (16.20); pyridine–water containing tetramethylammonium hydroxide (18.91); sulpholane–water containing tetramethylammonium hydroxide (19.18); dimethyl sulphoxide–water containing tetramethylammonium hydroxide (18.61); water containing lithium hydroxide (14.31).In addition to these results adjustments have been made to previously published scales for hydrazine–water (15.08) and ethylenediamine–water (15.48).Keywords
