Abstract

Aluminum monohydroxide, or seudobohemite,was obtained by reaction between aluminumand isopropyl alcohol using sol gel method.Two different catalysts were tested: mercuricIodide and sublimated iodine. The researchlooked for the influence of aging time and kindof catalysts changed textural properties in thesolid (superficial area, pore size and volume). Anenvironmental evaluation of the two processeswere carried out using Green Chemistry Expertsystem The results no show main effect inthe kind of catalyst in the solid properties andthe sublimated iodine was more friendly with theenvironment.
