摘要：

Vapor-liquid equilibrium has been determined at 94 and 70 kPa for the binary system methanol+ethyl 1,1-dimethylethyl ether. The system deviates positively from ideal behavior and presents a minimum boiling azeotrope at 329 K with 57% mole methanol (94 kPa) and at 322 K with 52% mole methanol (70 kPa). The activity coefficients and boiling points of the solutions were correlated with the mole fraction by the Wohl, Wilson, UNIQUAC, NRTL and Wisniak-Tamir equations.
