Viscosities for the binary liquid mixtures of methylethylketone with benzen, toluene, chlorobenzene, bromobenzene and nitrobenzene were determined at 303·15 K. The deviation in viscosity was calculated and its behaviour was studied as a function of mole fraction. The deviation in viscosity is negative in the system methylethylketone with benzene and is positive in the other systems. The results are discussed in terms of dipole-induced dipole and dipole-dipole interactions.
