Experimental data of isobaric vapour-liquid equilibrium for binary mixtures containing tetrahydrofuran and isomeric chlorobutanes

摘要

Isobaric vapour-liquid equilibrium (VLE) measurements for mixtures formed by tetrahydrofuran and isomeric chlorobutanes at 40.0 kPa (except for the mixture containing 2-methyl-2-chloropropane) and 101.3 kPa are reported. The activity coefficients were calculated from experimental data. The mixture containing 2-chlorobutane at 40.0 kPa presents an azeotrope. The VLE measurements have been found thermodynamically consistent according to A Van Ness test. Wilson, NRTL, and UNIQUAC equations have been used to correlate the activity coefficients and we have obtained satisfactory results.
