Isobutane alkylation catalyzed by supported perfluoroalkanedisulphonic acids

Isobutane alkylation catalyzed by supported perfluoroalkanedisulphonic acids

Silica supported perfluoroalkanedisulphonic acids (PFAS-SiO2) catalyze the alkylation of isobutane with n-butene to yield mainly high-octane trimethylpentanes. PFAS-SiO2 activity is highly dependent on the PFAS employed, on the preparation method and on the reaction conditions adopted. 1H and 29Si M...

Zusammenfassung:Silica supported perfluoroalkanedisulphonic acids (PFAS-SiO2) catalyze the alkylation of isobutane with n-butene to yield mainly high-octane trimethylpentanes. PFAS-SiO2 activity is highly dependent on the PFAS employed, on the preparation method and on the reaction conditions adopted. 1H and 29Si MAS NMR spectroscopy were used to evidence the changes in surface silanols caused by impregnating silica with perfluoroethanedisulphonic acid. A possible active species is hypothesized on the basis of the data acquired through NMR spectroscopy.
