Alumina modified by various fluorine containing compounds has been studied in reactions of nbutene. Combination of the results thus obtained with pieces of information from the literature leads to the following model. Skeletal isomerization takes place on Lewis acid sites as a monomolecular conversi

✦ Synopsis
A theoretical study was carried out in order to characterize the changes produced by the presence of sulfate on the alumina surface. A molecular orbital approach of the extended Hückel (EH) type together with dynamic molecular calculation were performed to evaluate adsorption and desorption energies of the intermediate species for skeletal and double-bond isomerization reactions of n-butene The bimolecular and monomolecular mechanisms for skeletal isomerization were evaluated.
