    Solution properties of C60 and C70 fullerenes and C21 to C40 n-alkanes at infinite dilution in carbon dioxide from supercritical fluid chromatography.

  • Original language description

    Retention factors of eleven heavy n-alkanes (C21H44, C22H46, C23H48, C24H50, C25H52, C27H56, C28H58, C31H64, C34H70 C36H74, and C40H82) and C-60 and C-70 fullerenes were measured within 311-431 K and 8.7-39 MPa by supercritical fluid chromatography in anopen tubular capillary column. This data set was obtained using a poly(methyl-n-octyl siloxane) stationary polymer and carbon dioxide as the mobile-phase fluid. The retention factors are employed to derive the partial molar volumes of the solutes at infinite dilution in CO2 and the infinite-dilution molar enthalpies of transfer of the solutes from the stationary phase to supercritical CO2. The partial molar volumes are subsequently transformed to quantities characterizing short-range solute-CO2 interactions, and the effects are shown of the corrections for dissolution Of CO2 in the stationary polymer on these quantities. Distinct differences between the n-alkane-CO2 and the fullerene-CO2 interactions have been found and discussed. Over
