Abstract

ABSTRACT This work reports experimental densities and sound speeds at (293.15, 298.15, 303.15, 308.15, and 313.15) K and viscosities at 298.15 K for the binary liquid mixtures methanol + pyridine, methanol + benzene, and pyridine + benzene over the entire range of compositions and atmospheric pressure. The excess properties, namely the excess molar volume , excess isentropic compressibility , and excess Gibbs energy for activation of viscous flow G* E were calculated from experimental data and are fitted to Redlich-Kister polynomials. The results obtained were discussed in terms of molecular interactions between the mixing components and structural effects.

期刊介绍： Physics and Chemistry of Liquids publishes experimental and theoretical papers, letters and reviews aimed at furthering the understanding of the liquid state. The coverage embraces the whole spectrum of liquids, from simple monatomic liquids and their mixtures, through charged liquids (e.g. ionic melts, liquid metals and their alloys, ions in aqueous solution, and metal-electrolyte systems) to molecular liquids of all kinds. It also covers quantum fluids and superfluids, such as Fermi and non-Fermi liquids, superconductors, Bose-Einstein condensates, correlated electron or spin assemblies. By publishing papers on physical aspects of the liquid state as well as those with a mainly chemical focus, Physics and Chemistry of Liquids provides a medium for the publication of interdisciplinary papers on liquids serving its broad international readership of physicists and chemists.
