Isothermal (vapour + liquid) equilibria in the binary and ternary systems composed of 2-propanol, 2,2,4-trimethylpentane, and 2,4-dimethyl-3-pentanone

(Vapour + liquid) equilibrium data in the three binary (2-propanol + 2,2,4-trimethylpentane), (2-propanol + 2,4-dimethyl-3-pentanone), (2,2,4-trimethylpentane + 2,4-dimethyl-3-pentanone) systems, and in the ternary (2-propanol + 2,2,4-trimethylpentane + 2,4-dimethyl-3-pentanone) system are reported. The data were measured isothermally at (330.00 and 340.00) K covering the pressure range (8 to 70) kPa. The binary (vapour + liquid) equilibrium data were correlated using the Wilson and NRTL equations by means of a robust algorithm for processing all isotherms together; resulting parameters were then used for calculation of phase behaviour in the ternary system and for subsequent comparison with experimental data. Azeotropic behaviour of the (2-propanol + 2,2,4-trimethylpentane) system was evaluated together with all available published data.

► We have measured new experimental isothermal data on (vapour + liquid) equilibria. ► Three binary and one ternary systems were investigated. ► Components: 2-propanol, 2,2,4-trimethylpentane, and 2,4-dimethyl-3-pentanone. ► Correlation of data with use of the Wilson and NRTL equation. ► Prediction of phase equilibria in ternary system based on binary data.
