Abstract
Vapor-liquid equilibrium for the binary system methanol + methyl 1,1-dimeth ylethyl ether has been measured at 50, 78.4, and 94 kPa. The system present s a minimum boiling point azeotrope that is enriched in the ether when the pressure decreases. The activity coefficients and boiling points of the sol utions were correlated with its composition by the Wohl, Wilson, UNIQUAC, N RTL, and Wisniak-Tamir equations.
