Catalyst compositions with improved alkylation activity and corresponding methods for making such catalyst compositions are provided. The catalyst(s) correspond to solid acid catalysts formed by exposing a catalyst precursor with a zeolitic framework structure to a molten metal salt that includes fluorine, such as a molten metal fluoride. The resulting fluorinated solid acid catalysts can have improved alkylation activity while having a reduced or minimized amount of structural change due to the exposure to the molten metal fluoride. This is in contrast to fluorinated solid acid catalysts that are exposed to higher severity forms of fluorination, such as exposure to ammonium fluoride or HF. SnF.sub.2 is an example of a suitable molten metal fluoride.
