ABSTRACT

Isobaric vapor liquid equilibria (VLE) of binary systems formed by 1-chloro-2-ethylhexane + 2-ethyl-1-hexanol as well as 1-chloro-2-ethylhexane or 2-ethyl-1-hexanol + p-xylene (PX), or N-methylpyrrolidone (NMP) were determined at a pressure of 40.0 kPa using a recirculating still. The Wilson, nonrandom two-liquid (NRTL), and universal quasichemical (UNIQUAC) activity coefficient models were used to describe the nonideality of the liquid phase. The vapor phase was regarded as ideal. The experimental data were checked with the Herington consistency and point consistency test methods, which showed thermodynamic consistency.
