Thermodynamics of fuels with a biosynthetic component (III): Vapor–liquid equilibrium data for the ternary mixture ethyl 1,1-dimethylethyl ether, n-heptane and 1-hexene at T = 313.15 K

Accurate vapor–liquid equilibria were measured for the ternary system ethyl 1,1-dimethylethyl ether + n-heptane + 1-hexene using an isothermal total pressure cell. The experimental data were well correlated using Wohl expansion and Wilson, NRTL and UNIQUAC models. The system shows a slight positive deviation from the ideality. A comparison with similar ternary systems containing other ethers is also discussed in the paper.
