Vapor-liquid equilibrium of octane-enhancing additives in gasolines 3. Total pressure data and g(E) for ternary mixtures containing di-isopropyl ether or benzene and n-heptane plus cyclohexane at 313.15 K
New experimental isothermal P-x data at T = 313.15 K for two ternary systems (di-isopropyl ether, (DIPE) + n-heptane + cyclohexane) and (benzene + n-heptane + cyclohexane) are reported. Data reduction by Barker's method provides correlations for g(E). The Wohl's expansion, as well as Wilson, NRTL and UNIQUAC models have been applied sucessfully to the ternary systems.
