Phase equilibrium properties of binary and ternary systems containing tert-amylmethyl ether (TAME) as oxygenate additive and gasoline substitution hydrocarbons at 313.15 K

Experimental isothermal P-x-y data for the binary systems (tert-amylmethyl ether (TAME) + the hydrocarbons n-heptane, cyclohexane, benzene and 1-hexen e) and the ternary system (tert-amylmethyl ether (TAME) + 1-hexene + cycloh exane) at 313.15 K are reported. Data reduction by Barker's method provides correlations for G(E) using the Margules equation for the binary systems a nd the Wohl expansion for the ternary system. Wilson, NRTL and UNIQUAC mode ls have been applied successfully to both the binary and the ternary system s presented here and they have been used for predicting the behaviour of th e other ternary systems involving TAME + hydrocarbon + hydrocarbon, where t he four types of substitution hydrocarbons have been used.
