Isobaric Vapor-Liquid-Equilibria of 1-Butanol Plus N,N-Dimethylformamide and 1-Pentanol Plus N,N-Dimethylformamide Systems at 50.00 and 100.00 kPa
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.
