Abstract: Densities of sodium chlorobenzoate(o-, m-, p-) were measured in solutions up to 80 weight percent dimethylformamide(DMF) at 298.15 K with an oscillating tube densimeter. From these densities, apparent molar volumes of sodium chlorobenzoate in DMF-H2O mixtures were calculated, and partial molar volumes at infinite dilution were evaluated. Substituent and solvent effects on transfer volumes of each isomer from water to DMF-H2O mixed solvents were obtained. The results are explained in terms of solvent structure and solute-solvent interaction.
Key words: Sodium chlorobenzoate, DMF-water mixed solvent, Volumetric property
