Vapor-liquid equilibria of methanol, ethanol, propan-2-ol, and 2-methylpropan-2-ol with a five-component hydrocarbon mixture at 101.3 kPa

Isobaric vapor-liquid equilibria (VLE) were measured at 101.3 kPa for the systems of methanol, ethanol, propan-2-ol, and 2-methylpropan-2-ol separately with a five-component hydrocarbon mixture. The relative volatilities of alcohol with respect to the hydrocarbon mixture were also derived. Analysis of the experimental VLE data exhibits a minimum boiling temperature for all the systems. The experimental data have been correlated with the mole fraction of alcohol using the Redlich-Kister and Wisniak-Tamir equations.
