Vapor liquid equilibria for ethanol + 2,4,4-trimethyl-1-pentene and 2-propanol + 2,4,4-trimethyl-1-pentene at 101 kPa

Isobaric vapor liquid equilibrium (VLE) data were measured for the systems ethanol + 2,4,4-trimethyl-1-pentene and 2-propanol + 2,4,4-trimethyl-1-pentene at 101 kPa. The measurements were made with a recirculation still. The determination of the equilibrium compositions was made with two analyzers, a mass spectrometer, and a gas chromatograph. Two novel sampling systems were tested for introducing the samples of liquid and condensed vapor phases to the analyzers. The VLE data were correlated with the Wilson activity coefficient model and the Soave−Redlich−Kwong equation of state.
