✦ Synopsis

This paper presents the results of the determination of various physical parameters of N-arylsubstitutedhydroxamic acids. These reagents behave as weak organic bases in the presence of strongly acidic solutions. Their protonation behaviour was studied in hydrochloric acid solutions. Relevant pK BH values were calculated according to the Hammett acidity function method, the Bunnett-Olsen method and the excess acidity method. Other physical parameters investigated were densities, molar volumes and partition data between different organic solvent-aqueous systems. An attempt was made to correlate these data with theoretical calculations based on regular solution theory and to investigate the solubility parameters of these reagents.
