Compressibility of liquid mixtures assuming incompressible cores

AuthorsResa López, Pablo Ismael ; Elvira Segura, Luis
Issue Date18-Sep-2009
CitationChemical Physics Letters 481 : 198–203 (2009).
AbstractA simple expression to evaluate the isothermal compressibility, adiabatic compressibility and sound velocity of liquid mixtures from excess volumes, considerably improving the predictions from ideal mixing rules, is proposed. This equation is based on the exclusion of ‘incompressible’ volumes for the calculation of compressibilities. The incompressible volumes of different compounds have been estimated by fitting the compressibility of binary mixtures. Consistent values have been found for all the substances analysed. The incompressible volumes obtained are compared to the excluded volumes of similar approaches.
