Isobaric vapor-liquid equilibrium for binary and ternary mixtures of 2-methyl-2-propanol plus methyl 1,1-dimethylpropyl ether plus 2,2,4-trianethylpentane

New consistent vapor-liquid equilibrium (VLE) data for the binary system methyl I,1-dimethylpropyl ether (TAME) + 2,2,4-trimethylpentane (isooctane) and the ternary system 2-methyl-2-propanol (TBA) + methyl 1,1-dimethylpropyl ether (TAME) + 2,2,4-trimethylpentane (isooctane) are reported at 101.3 kPa. In the binary system, the results indicate a positive deviation from ideality and no azeotrope is present. The ternary system presents a saddle point azeotrope that can be predicted from binary data. The activity coefficients and boiling points of the solutions were correlated with their composition by Wilson, UNIQUAC and NRTL equations. (C) 2000 Elsevier Science B.V. All rights reserved.
