Abstract
Densities of sodium chlorobenzoate(o-, m-, p-) have been measured in soluti ons up to 80%(mass fraction) dimethylformamide (DMF) at 298.15 K with an os cillating-tube densimeter. From these densities, apparent molar volumes of sodium chlorobenzoate in DMF-H2O mixtures have been calculated, and partial molar volumes at infinite dilution have been evaluated. Substituent and so lvent effect on transfer volumes of each isomer from water to DMF-H2O mixed solvents have also been obtained. The results are explained in terms of so lvent structure and solute-solvent interaction.
