Measurements of Density, Dynamic Viscosity, Refractive Index and excess properties to Investigate Molecular Interactions in the Binary Mixture of Ethyl Benzoate and 2-Butanol from 303.15 K to 313.15 K

Abstract

The thermochemical characteristics of binary mixture of ethyl benzoate (EB) and 2-Butanol (2-BuOH) over the entire composition range at temperatures between 303.15 K and 313.15 K under atmospheric pressure have been measured. Excess molar volume V^E, excess Gibbs energies of activation of viscous flow ΔG^*E, excess viscosity deviations Δη and, and deviation in refractive indices Δn_D, were calculated then fitted to the Redlich- Kister polynomial equation. In the chemical and biochemical industries, these results can be used to create detailed theoretical models for the design of various technological processes. The values estimated by theoretical procedure and the experimental one showed good agreement. The intermolecular interactions have been used to explain the deviations for excess characteristics.
