Partial molar volumes and viscosity B coefficients of benzyltriethylammonium chloride in dimethyl sulfoxide plus water at different temperatures

The viscosities of solutions of benzyltriethylammonium chloride have been measured in dimethyl sulfoxide (DMSO) + water mixtures at various temperatures (298, 303, 308, 313, and 318 K). The results have been analyzed using the Jones-Dole equation, and the viscosity B coefficients have been calculated. The density data have been analyzed using Masson's equation. The partial molar volume V-phi(o) at infinite dilution and the slopes V-s(*) of Masson's equation at different compositions of DMSO have been interpreted in terms of solute-solvent and solute-solute interactions, respectively.
