• Density
• Excess molar volumes
• Interactions

Densities of binary mixture of N, N-dimethylformamide (DMF) + 1-Butanol were determined using a vibrating-tube densimeter DMA 5000, over the entire range of molar fractions in the range temperatures from 283.15 K to 313.15 K and 1.011 bar. Excess molar volumes (V-m(E)), partial molar volumes ((V) over bar (i)), partial molar volumes at infinite dilution ((V) over bar (infinity)(i)), excess partial molar volumes ((V) over bar (E)(i)) of the solute and solvent were calculated. The excess molar volumes were correlated using the Redlich-Kister equation. Additionally, the virial coefficients (bv) were calculated according to the McMillan-Mayer theory. The values obtained for these parameters were discussed in terms of the interactions present in solution.
