Popis:	The adsorption properties of γ-Al2O3 were studied using gas chromatography. Isotherms of adsorption of n-alkanes (C6–C9), hex-1-ene, benzene, and isobutanol were measured within 70–100°C. The isosteric heats of adsorption and contributions to them from dispersion (Δq dis) and specific (Δq sp) interactions were determined for hex-1-ene, benzene, and isobutanol. Under the conditions covered, hex-1-ene molecules are adsorbed mainly on account of dispersion interactions. For the adsorption of benzene, Δq dis is nearly twice as large as Δq sp, while for the adsorption of isobutanol, Δq sp is nearly twice as large as Δq dis. At 100°C, isobutyl alcohol is chemisorbed.
