Volumetric properties, viscosities and refractive indices of binary mixed solvents containing methyl benzoate

Abstract

Densities, dynamic viscosities, and refractive indices of the binary mixed solvents of methylbenzoate with a set of eleven organic solvents provided with six carbon atoms but different structure and functional groups were measured over the whole composition range. Thermodynamic, transport, solubility, and electrical properties were analyzed for all systems; from the experimental quantities, excess and mixing properties were deduced and interpreted in terms of intermolecular interactions and structural changes upon mixing. Mixing viscosities and excess Gibbs energies of activation for viscous flow support the role played by the size of the cosolvent on the mixture behaviour. Analysis in terms of solvent solubility parameters was in convincing good agreement with experimental results. The Soave and Peng–Robinson equations of state and the Wong–Sandler mixing rule are used to correlate volumetric properties. The predictive ability of several one-parameter and two-parameter viscosity models was also tested.
