|Abstract:||Viscosities of the polar molecule, dichloromethane in mixtures with nonpolar solvents cyclohexane, benzene, p-xylene and mesitylene have been measured at two different temperatures 293.15 K and 303.15 K. The viscosities of binary liquid mixtures prepared with cyclohexane show appreciable negative deviation from rectilinear dependence on mole fraction of dichloromethane. This deviation decreases in the case of benzene and p-xylene and becomes positive for the binary mixture with mesitylene. The deviation is positive even for the binary mixture with p-xylene at 303.15 K. An attempt has been made to correlate the deviation of viscosity from the rectilinear dependence, the parameters d of Grunberg-Nissan equation and C of Hind-McLaughlin-Ubbelohde equation and the interchange energy Wvisc with the degree of interaction. It is found that the value of C is more consistent than the value of d.|
