Excess molar volumes for the ternary mixture N,N-dimethylformamide (DMF) + methanol + water and for the binary constituents, DMF + water, DMF + methanol and methanol + water at 298.15 K are reported. Several empirical expressions are used to predict and correlate the ternary excess molar volumes from experimental results on the constituent binaries. A pseudo binary mixture approach is used to analyze the system studied. The partial molar volumes of methanol at infinite dilution in DMF + water mixed solvent at several fixed compositions were evaluated and correlated with the composition.
