High-Pressure Vapor−Liquid Equilibria for Propane + 2-Butanol, Propylene + 2-Butanol, and Propane + 2-Butanol + 2-Propanol

Vapor−liquid equilibria have been measured for propane + 2-butanol, propylene + 2-butanol, and propane + 2-butanol + 2-propanol in the temperature range of (328.1 to 368.1) K and at pressures up to 44.45 bar. The data were correlated using a group contribution equation of state for associating mixtures.
