Plot of deviation in isentropic compressibility,Δκ_s, for the binary mixtures: (a) {2,5-DMF (1)+FA (2)}; (b) {2,5-DMF (1)+MIBK (2)}; (c) {2,5-DMF (1)+1-butanol (2)} and (d) {2,5-DMF (1)+2-butanol (2)} as function of the composition expressed in the mole fraction at 293.15 K (♦); 303.15 K (■); 313.15 K (▲) and 323.15 K (●). The dotted lines were generated using Redlich-Kister polynomial curve-fitting.
