摘要：
Solid acids catalysts based on perfluoroalkanedisulphonic acid supported on silica (PFAS-SiO2) catalyse the alkylation of isobutane with n-butene to yield high-octane gasoline components. PFAS-SiO2 activity is highly dependent on the PFAS employed, on the preparation method and on the reaction conditions adopted. H-1 and Si-29 MAS NUR spectroscopy were used to evidence the changes in surface silanols caused by impregnating silica with perfluoroethanedisulphonic acid.
