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

摘要

Isothermal P-x data (vapor-liquid equilibrium (VLE) and excess enthalpy data (H~E) 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 computercontrolled 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 hte experimental VLE nad H~E 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 ehtanol, 2-methyltetrahydrofuran, and light hydrocarbons.
