Abstract
Consistent vapor-liquid equilibrium data for the binary and ternary systems 2-methyl-2-propanol (TBA) + methyl 1,1-dimethylpropyl ether (TAME) at temp eratures from 353 to 359 K and 2-methylpentane + 2-methyl-2-propanol (TBA) + methyl 1,1-dimethylpropyl ether (TAME) from 332 to 353 K are reported at 101.3 kPa. The results indicate that the systems deviate positively from id eality and that only the binary system presents an azeotrope. The ternary s ystem is well predicted from binary data. The activity coefficients and boi ling points of the solutions were correlated with composition by Wilson, UN IQUAC, NRTL, and Wisniak-Tamir equations.
