ABSTRACT

Isobaric vapor-liquid equilibria (VLE) were measured at atmospheric pressure for the ternary system methanol + 2-propanol + 2-methyl-2-butanol and its constituent binary system 2-propanol + 2-methyl-2-butanol. Parameters for the Wilson, NRTL, and UNIQUAC equations were determined from the binary VLE data, and the prediction for ternary VLE system was compared with experimental results. For both binary and ternary systems, the NRTL and UNIQUAC models gave good predictions.
