Organized mesoporous aluminas were synthesized from aluminium sec-butoxide and lauric or steric acid as structure-directing agent and characterized by adsorption of nitrogen and X-ray powder diffraction. Adsorption data analysis based on the comparison of adsorption isotherm of nitrogen at -196.DEG.C on mesoporous aluminas with the standard adsorption isotherm of nitrogen on a reference non-porous solid seems to be the promising approach to characterize these not completely regular materials. These data were transformed to the statistical film thickness curve and further used to calculate of Barrett-Joyner-Halenda pore size distributions.
