Comparative Analysis For Pseudoboehmite Obtained By Sol Gel Using Green Chemistry Expert System software

摘要

The research was aimed to analyze whether the aging time and type of catalyst used in obtaining isopropoxide have any effect on the textural characteristics of the solid (surface area, pore size and volume) obtained in the end. The initial alkoxide was processed by the technique proposed by BE Yoldas. The reactants were analizated by infrared and the product were characterizated by TGA, XRD, surface area, pore volumen and pore size. The results of area, pore size and volume were analyzed with the software Desing Expert, to determine whether those factors had influence in these three variables. Finally, environmental analysis was performed comparing the two methods of synthesis of aluminum alkoxide in order to know the amount of waste produced by each of the catalysts and thus to establish which of the two is more environmentally friendly . For this purpose the simulation package Green Chemistry Expert System was used.
