Vapor−Liquid Equilibria and Excess Enthalpy Data for the Binary Systems 2-Methyltetrahydrofuran with 2,2,4-Trimethylpentane (Isooctane), Ethanol, Toluene, Cyclohexane, and Methylcyclohexane

Abstract

Isothermal P−x data (vapor−liquid equilibrium (VLE)) and excess enthalpy data (HE) for the five binary systems 2-methyltetrahydrofuran with 2,2,4-trimethylpentane (isooctane), ethanol, toluene, cyclohexane, and methylcyclohexane are presented. The VLE data were obtained experimentally, in a computer-controlled static apparatus, and the heat of mixing data were measured in an isothermal flow calorimeter. Also presented are linear temperature-dependent interaction parameters for the NRTL and UNIQUAC models which were fitted simultaneously to the experimental VLE and HE data. These data and the correlation parameters should be useful for predicting properties, e.g., volatility (Reid vapor pressure (RVP), etc.) of blends of alternative automotive fuels which contain ethanol, 2-methyltetrahydrofuran, and light hydrocarbons.
