Abstract

Abstract Eleven monosubstituted diphenylamines have been synthetized, and concentration ratio of the protonated and free bases has been measured in aqueous sulphuric acid in the concentration range 1.0. 10-3 to 9.0 mol l-1. An algorithm has been suggested and used for determination of optimized values of pK and H''acidity function within sulphuric acid concentration range 0.05 to 9.0 mol l-1. The results have been compared with literature ...
