(Vapour + liquid) equilibria and excess molar enthalpies for mixtures with strong complex formation. Trichloromethane or 1-bromo-1-chloro-2,2,2-trifluoroethane (halothane) with tetrahydropyran or piperidine

Popis výsledku v původním jazyce

Isothermal vapour + liquid equilibria were measured for {trichloromethane + tetrahydropyran or piperidine} at 333.15 K and {1-bromo-1-chloro-2,2,2-trifluoroethane (halothane) + tetrahydropyran or piperidine} at 323.15 K using a circulation still. The results were verified by effective statistical procedures and used to calculate activity coefficients and excess molar Gibbs free energies. Excess molar enthalpies for these mixtures were determined at 298.15 K by means of an isothermal CSC microcalorimeterequipped with recently reconstructed flow mixing cells. Reliable performance of the calorimetric setup was proved by measurements of excess molar enthalpies for (hexane + cyclohexane), (2-propanone + water) and (methanol + water) comparing the results with best literature data. The trichloromethane or halothane containing mixtures exhibit strong negative deviations from Raoult's law and are highly exothermic, thus indicating that the complex formation via hydrogen bonding is a governing
