Vapor-liquid equilibrium data are needed for the reformulation of gasoline to meet Federal Clear Air Act standards. Oxygenates, such as ethers and alcohols, are known to reduce Co emissions from motor vehicles, and ethers are used as a substitute for aromatics in gasoline to improve the octane rating. The vapor pressure of pure tert-amyl methyl ether (TAME) was measured together with isothermal P-x data for mixtures of pentane + TAME and pentane + tert-amyl alcohol (TAOH) at temperatures between 70 and 110 C. Also, activity coefficients at infinite dilution for the binary mixtures of TAME + TAOH were obtained in the 90--120 C temperature range. The P-T-x data were correlated using the Peng-Robinson equation of state separately with the van der Waals and Wong-Sandler mixing rules.
