Interaction second virial coefficients for (CO2 + n-CmH2m+2) with (m = 21 to 40) from supercritical fluid chromatography.
Original language description
Partial molar volumes of 11 n-alkanes (C21H44, C22H46, C23H48, C24H50, C25H52, C27H56, C28H58, C31H64, C34H70, C36H74, and C40H82) at infinite dilution in CO2, obtained previously by supercritical fluid chromatography within T = 310.5 K to T = 431.6 K and within p = 8.7 MPa to p = 39.1 MPa, have been used to estimate the CO2(1)alkane(2) interaction second virial coefficients B12. The isothermal, high-pressure data are fitted by the PengRobinson equation of state with the van der Waals one-fluid mixing rules, and the optimised unlike-interaction parameters of the equation are used to calculate B12. The effects are discussed of the various error sources inherent in this model-dependent procedure on the resultant estimates of B12.
