The partial solubility parameters of cellulose and AKD (Alkylketene dimer) treated paper were determined by inverse gas chromatography. The Snyder/Karger-Hansen interaction model was used, where -#x394;EA= Vi#x3B4;ld+ #x3B4;lp#x3B4;jp+ #x3B4;jh#x3B4;jh). The adsorption internal energies of a series of n-alkanes and five polar probes were measured. From the #x394;EAvalues of n-decane, acetone and THF, which give the largest normalized determinant M(n), the partial solubility parameters of the stationary phases were calculated. The partial solubility parameters of cellulose were: #x3B4;d= 8027; #x3B4;p= 8.00; #x3B4;h= 13.88; #x3B4;t= 18.03 cal#xBD;/cm3/2AKD treated paper gave #x3B4;d= 8.10, #x3B4;p= 12.35, #x3B4;h= 7.96, and #x3B4;t= 16.78 cal#xBD;/cm3/2.
