Densities, Viscosities, and Refractive Indices of Binary Liquid Mixtures of Hexane, Decane, Hexadecane, and Squalane with Benzene at 298.15 K

Densities, ρ, viscosities, η, and refractive indices, n<INF>D</INF>, for binary mixtures of hexane, decane, hexadecane, and squalane with benzene were measured over the whole composition range at 298.15 K and atmospheric pressure. The excess molar volumes, <EQUATION><EQNDATA>%@mt;sys@%%@ital@%V%@rsf@%%@sx@%m%@be@%E%@sxx@%%@mx@%</EQNDATA> </EQUATION>, and viscosity deviations, δη, were calculated from experimental measurements. These result were further fitted to the Redlich−Kister equation to estimate the binary coefficients and standard errors. The effects of chain length and branching of alkanes on <EQUATION><EQNDATA>%@mt;sys@%%@ital@%V%@rsf@%%@sx@%m%@be@%E%@sxx@%%@mx@%</EQNDATA> </EQUATION> and δη values have been discussed.
