The densities and viscosities of N-phenylbenzohydroxamic acid (PBHA) have been determined as a function of concentration in dimethylsulfoxide (DMSO) at various temperatures, (298.15, 303.15, 308.15, 313.15, and 318.15) K. The density data have been analyzed using Masson's equation, and partial molar volume (V-phi(0)) at infinite dilution and the slope S-v(*) of Masson's equation are computed. The limited partial molar expansibilities (phi(0)(E)) have also been calculated from the temperature dependence of limiting partial molar volume(V-phi(0)). The viscosity data have been analyzed using the Jones-Dole equation, and the viscosity B-coefficients are calculated. The results have been discussed in terms of solute-solvent interaction, and it was found that PBHA acts as a structure maker in the present system.
