Ion exchange resins are used in organic synthesis, e.g. for esterification and hydrolysis. Being high surface area and insoluble, they are suitable for vapor-phase and liquid-phase reactions. Examples can be found where basic (OH--form) of ion exchange resins are used to neutralize of ammonium salts and convert quaternary ammonium halides to hydroxides. Acidic (H+-form) ion exchange resins have been used as solid acid catalysts for scission of ether protecting groups and for rearrangement reactions.
