Abstract
The saturated vapor pressures of furfural (FUR), 2-acetylfuran (2AF), and 5-methylfurfural (5MF) and the isobaric vapor–liquid equilibrium (VLE) data for three binary systems (FUR + 2AF, FUR + 5MF, and 2AF + 5MF) at 3.60 and 5.18 kPa were experimentally measured in a Rose–Williams still. The saturated vapor pressures were correlated by the Antoine equation; the binary VLE data were correlated by the nonrandom two-liquid, Wilson, and universal quasichemical models. The VLE of the ternary system of FUR + 2AF + 5MF was predicted by the obtained binary interaction parameters for each model, and the predictions fit well with the experimental data.
