Excess Thermodynamic Properties of 1, 5-Pentanediol and Dimethyl Sulfoxide Binary Mixture At 313.15 K And 318.15 K

Abstract

Experimental measurements of density and viscosity of binary liquid mixture with 1, 5-Pentanedioland Dimethylsulfoxideas its components were made at T= (313.15 and 318.15) K and at atmospheric pressure for samples of different compositions. Excess thermodynamic properties namely excess molar volume (VE), viscosity deviation (??) and excess Gibbs energy of activation (GE) were computed from the experimental data. These properties were then fitted to Redlich-Kister equation for calculating coefficients and standard deviations. Variation of these properties with composition and temperature has been analyzed for the possible intermolecular interactions in the binary mixture.
