The experimental determinations of vapor-liquid equilibria (VLE) are indispensable for the design of separation processes such as distillation columns, extractive distillation, and selection of solvents. Isobaric vapor-liquid equilibria were obtained for the 1-butanol + N,N-dimethylformamide and 1-pentanol + N,N-dimethylformamide systems at 50.00 and 100.00 kPa. The activity coefficients were found to be thermodynamically consistent. The data were correlated with five liquid phase activity coefficient models (Margules, Van Laar, Wilson, NRTL, and UNIQUAC). Experimental vapor pressures of N,N-dimethylformamide are also included.
