Liquid-liquid equilibria of N-formylmorpholine (NFM) with alkanes (n-hexane, n-heptane, isononane), aromatics (benzene, p-xylene, toluene), and water were investigated. The experiments were conducted by considering binary, ternary, and quaternary systems at different temperatures (20-60 degrees C) and initial mixture compositions in the range of mole fraction equal to 0.3-0.6 for NFM, 0.23-0.4 for alkanes, 0.11-0.4 for aromatics, and 0.072-0.24 for water, respectively. The results are used to estimate the interaction parameters of the UNIQUAC expression, for the pairs NFM/n-hexane, NFM/n-heptane, NFM/isononane, NFM/benzene, NFM/p-xylene, NFM/toluene, and NFM/water whose values were not available in the literature.

Abstract
Liquid-liquid equilibria of N-formylmorpholine (NFM) with alkanes (n-hexane, n-heptane, isononane), aromatics (benzene, p-xylene, toluene), and water were investigated. The experiments were conducted by considering binary, ternary, and quaternary systems at different temperatures (20-60 degrees C) and initial mixture compositions in the range of mole fraction equal to 0.3-0.6 for NFM, 0.23-0.4 for alkanes, 0.11-0.4 for aromatics, and 0.072-0.24 for water, respectively. The results are used to estimate the interaction parameters of the UNIQUAC expression, for the pairs NFM/n-hexane, NFM/n-heptane, NFM/isononane, NFM/benzene, NFM/p-xylene, NFM/toluene, and NFM/water whose values were not available in the literature.
