A chromatographic technique was used to measure experimental capacity factors for the n-alkanes from C{sub 9}H{sub 20} to C{sub 36}H{sub 74} in CO{sub 2} from 308.2 to 348.2 K and from 100 to 240 bar. Infinite dilution activity coefficients, {gamma}{sub i}{sup {infinity}}, were calculated for the solid n-alkanes (C{sub 24}H{sub 50} to C{sub 36}H{sub 74}) utilizing regular solution theory to characterize the stationary phase. This allowed the estimation of solubilities from capacity factors for the solid n-alkanes in CO{sub 2}.
