Efficient carbon-based acid catalysts for the propan-2-ol dehydration

Abstract Halogenated activated carbons (AC–Hal, Hal = F, Br and Cl) used as precursors were functionalized with SO 3 H groups to prepare (AC–Hal–S) solid acid catalysts. ACs obtained were subjected to chemical and elemental analysis, characterized by miscellaneous physicochemical techniques and were tested in the propan-2-ol dehydration. The high catalytic activity of AC–Hal–S (Hal = F, Cl) is attributed to the presence of F and Cl affect on the catalysts performance and stability at the operation conditions.
