ABSTRACT
The binary liquid-liquid equilibrium (LLE) data for the system N-methylformamide (NMF) + n-hexadecane from (288.15 to 318.15) K and the ternary LLE for the systems NMF + heterocyclic nitrogen compounds (quinoline, pyridine, pyrrole, aniline, indole) + n-hexadecane at 298.15 K were analytically determined at atmospheric pressure by the use of stirred and thermoregulated cells. Experimental data were correlated with the NRTL and UNIQUAC activity coefficient models. The reliability of the measured LLE data were tested using the Bachman-Brown, Hand, and Othmer-Tobias equations. In addition, the extraction capability of NMF for heterocyclic nitrogen compounds was investigated with respect to distribution and selectivity.
