Excess volumes for the binary liquid mixtures of methylisobutylketone with benzene, toluene, chlorobenzene, bromobenzene, and nitrobenzene have been measured at 303.15 and 313.15 K. Excess volumes were negative for all the systems over the entire range of composition and at both the temperatures. The behaviour of VE as a function of composition and temperature was studied. Viscosity data have also been determined for the five systems at 303.15 K. The excess viscosity, Δ ln η, has been calculated and its behaviour as a function of composition was investigated. The results of VE and Δ ln η have been discussed in terms of dipole – induced dipole and dipole–dipole interactions between the components. VE and Δ ln η were analysed in the light of Prigogine–Patterson–Flory equation of state theory and Bloomfield and Dewan's viscosity relations.
