Excess molar volumes for ternary mixture (N,N-dimethylformamide+1-propanol+water) at the temperature 298.15 K

The results of excess molar volumes for ternary mixture N,N-dimethylformamide (DMF)+1-propanol+water and for binary constituents, DMF+water, DMF+1-propanol and 1-propanol+water at 298.15 K are reported. Several empirical expressions were used to predict and correlate the ternary excess molar volumes from experimental results on the constituent binaries. A pseudo-binary mixture approach (PBMA) was used to analyze the system studied. The partial molar volumes of 1-propanol at infinite dilution in [fmDMF+(1−fm)water] mixed solvents at their several fixed composition fm were evaluated and correlated with the composition fm.
