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.

糠醛，2-乙酰基呋喃和5-甲基糠醛的二元体系在3.60和5.18 kPa的蒸气压和等压蒸气-液体平衡

三种二元系统（FUR + 2AF，FUR + 5MF和2AF）的糠醛（FUR），2-乙酰基呋喃（2AF）和5-甲基糠醛（5MF）的饱和蒸气压以及等压蒸气-液体平衡（VLE）数据在Rose–Williams蒸馏瓶中通过实验测量了3.60和5.18 kPa的+ 5MF）。饱和蒸气压与Antoine方程相关。二元VLE数据通过非随机两液模型，Wilson模型和通用拟化学模型进行关联。通过获得的每个模型的二元相互作用参数预测了FUR + 2AF + 5MF三元系统的VLE，并且该预测与实验数据非常吻合。
