    Abstract: A novel metal organic framework, EMM-33, is described having the structure of UiO-67 and comprising bisphosphonate linking ligands. EMM-33 has acid activity and is useful as a catalyst in olefin isomerization. Also disclosed is a process of making metal organic frameworks, such as EMM-33, by heterogeneous ligand exchange, in which linking ligands having a first bonding functionality in a host metal organic framework are exchanged with linking ligands having a second different bonding functionality in the framework.

    Abstract: 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. SnF2 is an example of a suitable molten metal fluoride.
