• Resumen

  • Densities, refractive indices, and speeds of sound at 298.15 K, and isobaric vapor−liquid equilibria data at 101.3 kPa were reported for the binary mixtures 2-methyl-1-propanol + 2-methyl-1-butanol, 2-methyl-1-propanol + 3-methyl-1-butanol, and 2-methyl-1-propanol + 1-pentanol. VLE experimental data were tested for thermodynamic consistency by means of the Dechema test and were demonstrated to be consistent. The activity coefficients were correlated with the Margules, van Laar, UNIQUAC, NRTL, and Wilson equations. The ASOG model also was used for prediction. Examining the results, three systems have near ideal behavior.
