Halogenated activated carbons (AC–Hal, Hal = F, Br and Cl) used as precursors were functionalized with SO3H 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.
