ABSTRACT

Densities and viscosities of binary mixtures of n-decane with hexan-2-ol, heptan-2-ol and octan-2-ol have been measured over the entire range of composition at T = 298.15 K and at atmospheric pressure. From the experimental values of density and viscosity, the excess molar volumes () and excess Gibbs energy of activation of viscous flow () have been calculated. These results were fitted to Redlich.Kister polynomial equations to estimate the binary coefficients and standard errors. Jouyban.Acree model is used to correlate the experimental values of density, viscosity and ultrasonic velocity at T = 298.15 K. The results of the viscosity-composition are discussed in the light of various viscosity semi-empirical equations. The experimental results have been used to test the applicability of the Prigogine.Flory.Patterson (PFP) theory. The values of [delta]ln([eta]) have also been analysed using Bloomfield and Dewan model. The experimental and calculated quantities are used to study the nature of mixing behaviour between the mixtures.
