Abstract: | Ternary excess molar enthalpies HEm at 298.15 K and atmospheric pressure measured in a flow microcalorimeter are reported for the methanol+2-propanol+methyl t-butyl ether (MTBE) and ethanol+1-propanol+MTBE systems. The ternary results have been correlated by means of a polynomial equation and used to construct constant excess enthalpy contours. Furthermore, the results have been compared with those calculated from a UNIQUAC associated-solution model taking into account molecular association of alcohols and solvation between unlike alcohols and alcohols with MTBE using only binary information. |
