ABSTRACT

New isobaric vapor liquid equilibria data were measured for N,N-dimethyl-1-butanamine + n-hexane, n-heptane, 1-propanol, 1-butanol, or 1-pentanol and N,N-dimethyl-1-octanamine + n-heptane or 1-butanol binary mixtures. The boiling temperatures of both pure amines were also investigated. For this, an ebulliometer based on Cottrell s apparatus was used. Thus, 180 new mixture data points displayed on 35 isobars were obtained in a pressure range from (29.84 to 99.83) kPa and in the full composition range. The experiments were compared with the Group contribution polar perturbed chain statistical associating fluid theory (GC-PPC-SAFT) equation of state predictions for pure amines and the mixtures containing an alkane. In the case of the systems containing an alkanol, the binary interaction parameters needed to be fitted.
