Abstract

Excess molar enthalpies, measured at 298.15 K in a Calvet microcalorimeter, are reported for {x1tert-butyl methyl ether (MTBE)+x2ethanol (EtOH)+(1−x1x2)heptane}. Smooth representations of the results are presented and used to construct contant excess molar enthalpy contours on Roozeboom diagrams.

Keywords
