(VAPOR PLUS LIQUID) EQUILIBRIA OF (1-BROMO-1-CHLORO-2,2,2-TRIFLUOROETHANE (HALOTHANE) PLUS AN OXYGENATED SOLVENT OR HEXANE)

Isothermal (vapour + liquid) equilibria (p, T, x, y) were measured for {1-bromo-1-chloro-2,2,2-trifluoroethane (halothane) + propan-2-one or methyl ethanoate or methyl 1,1-dimethylethyl ether or tetrahydrofuran or hexane} at T = 308.15 K by a dynamic method. Excess molar volumes were determined for {halothane = methyl 1,1-dimethylethyl ether or hexane} by calculating from density measurements at T = 298.15 K. The results obtained for the (vapour = liquid) equilibria were verified by effective statistical procedures and used to calculate activity coefficients and excess Gibbs free energies. the results indicate strong specific interaction of halothane with oxygenated compounds. © 1993 Academic Press Ltd.
