Excess Volumes, Viscosities and Refractive Index for the Binary Mixtures of Acetophenone, Cyclopentanone, Cyclohexanone and 3-pentanone with Dibutyl Maleate at T = (303.15, 308.15 and 313.15) K

Abstract

Density, viscosity and refractive index of some binary mixtures of dibutyl maleate with acetophenone, cyclopentanone, cyclohexanone, and 3-pentanone have been measured over the entire composition range at (303.15, 308.15 and 313.15) K and at atmospheric pressure. Excess volume (V E ) and deviation in viscosity () have been estimated from the experimental data of density and viscosity. The results of excess properties are interpreted in terms of molecular interactions. These results were fitted to Redlich-Kister polynomial equation to estimate the binary coefficients and standard errors. Further the values of (V E ) have been analyzed using Prigogine-FloryPatterson (PFP) theory. Refractive index composition data are discussed in the light of various equations suggested by Lorentz-Lorentz, Weiner and Newton. The mixture viscosities have also been correlated using Auslaender and Krishnan-Laddha models.
