Vapour–liquid equilibrium of octane-enhancing additives in gasolines ☆: 2. Total pressure data and gE for binary and ternary mixtures containing tert-amylmethyl ether (TAME), tert-amyl alcohol (TAOH) and n-hexane
2001
Abstract Vapour–liquid equilibria of the ternary system ( tert -amylmethyl ether (TAME)+ tert -amyl alcohol (TAOH)+ n -hexane) and for their constituent binary systems have been measured at 313.15 K. Data reduction by Barker’s method provides correlations for g E using the Margules equation for the binary systems and the Wohl expansion for the ternary system. Wilson, NRTL and UNIQUAC models have been applied successfully to both the binary and the ternary systems. Moreover, we compare the experimental results for these binary mixtures to the prediction of the UNIFAC (Dortmund) model. Experimental results have been compared to predictions for the ternary system obtained from the Wilson, NRTL, UNIQUAC and UNIFAC models. The presence of azeotropes in the binary systems has been studied.
