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. (c) 2007 Elsevier B.V. All rights reserved.
