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
Journal Title: International Journal of engineering Research and Applications - Year 2017, Vol 7, Issue 4
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.
