ABSTRACT

In this research, vapor liquid equilibrium (VLE) data were determined at 318.15 K for the mixtures propan-1-ol + 2,2,4-trimethylpentane and butan-1-ol + 2,2,4-trimethylpentane in an isothermic Othmer still with recirculation, where the temperature was kept constant by means of a proportional-integral (PI) cascade control for the vapor phase. The equilibrium concentration for each phase was determined by gas chromatography, and the vapor phase was considered as nonideal. The consistency of the data was verified by means of the Van Ness direct test of thermodynamic consistency, supported by several thermodynamic methods based on the Gibbs Duhem equation. The correlation of the VLE data was carried out using the Wilson local composition model. The alkanol + 2,2,4-trimethylpentane mixtures studied exhibit positive contributions from ideality and azeotropic behavior.
