Excess enthalpies of binary mixtures containing halothane + methyl alkyl ketones

Molar excess enthalpies H E of binary liquid systems of halothane (2-bromo-2-chloro-1,1,1-trifluoroothane)+five methyl alkyl ketones (2-alkanones) have been determined with a flow microcalorimeter at 298.15 K and at atmospheric pressure in the entire composition range. The data were correlated by means of the Redlich-Kister expression. All these mixtures are strongly exothermic with a minimum of H E of ca. -2900 J mol -1 at nearly equimolar composition
