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 kPa 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 NRTL, Wilson, and UNIQUAC 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.
