Abstract

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.
