Abstract
The studies of density (ρ), Viscosity (η) and refractive index (nD) are being
increasing used as tools for investigation of the properties of pure component and the
nature of intermolecular interactions between the liquid mixture constituents.
Experimental results of density (ρ), Viscosity (η) and refractive index (nD) of binary
liquid mixtures of (benzene+n-hexane), (benzene+toluene), (benzene+chloroform) and
(benzene +carbontetra chlorid) have been determined for varying mole fraction of
solvents components at 293,298, and 303 K under atmospheric pressure. The viscosity
of these binary mixtures were calculated theoretical from pure component data by using
various empirical relation.RM for pure component and Rm of binary component were
calculated from density and refractive index of pure solvents. The results are farther
discussed intermolecular interaction and structural of properties of binary liquid
mixtures. The structural variation of binary mixtures have been discussed on the basis of
the change in viscosity. The variation of these parameters with composition and
temperature of the mixtures have been discussed in term of molecular interaction in the
mixtures.
