Abstract
Vapor-liquid equilibria for methanol + 1,1-dimethylpropyl methyl ether (tert-amyl methyl ether or TAME) have been measured at (288.15, 308.1 5, and 328.15) K. A Gibbs-Van Ness type apparatus for total vapor pres sure measurements has been used. The system shows positive deviations from Raoult's law with an azeotrope, whose coordinates are reported at the three temperatures studied. Results have been analyzed in terms o f the UNIQUAC model, several versions of the UNIFAC model, and the mod ified-Huron-Vidal second-order (MHV2) group contribution equation of s tate.
