Gas-liquid partitioning of halogenated volatile organic compounds in aqueous cyclodextrin solutions

Original language description

Gas-liquid partitioning coefficients (K_GL) were measured for halogenated volatile organic compounds (VOCs), namely 1-chlorobutane, methoxyflurane, pentafluoropropan-1-ol, heptafluorobutan-1-ol, alpha,alpha,alpha-trifluorotoluene, and toluene in aqueoussolutions of natural alpha-, beta-, and gamma-cyclodextrins (CDs) at temperatures from (273.35 to 326.35) K employing the techniques of headspace gas chromatography and inert gas stripping. The binding constants of the 1:1 inclusion complex formation between the VOCs and CDs were evaluated from the depression of the VOCs volatility as a function of CD concentration. The host?guest size matching and the hydrophobic interaction concept were used to rationalize the observed widely different affinity of theVOC-CD pairs to form the inclusion complex. The enthalpic and entropic component of the standard Gibbs free energy of complex formation as derived from the temperature dependence of the binding constant indicate the thermodynamic origin
