Abstract: Densities of sodium chlorobenzoate(o-, m-, p-) have been measured in solutions up to 80% (mass fraction) dimethylformamide (DMF) at 298.15 Kwith an oscillating-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 solvent 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 solvent structure and solute-solvent interaction.

Key words: Sodium chlorobenzoate, DMF-water mixed solvent, Volumetric properties
