Application

3-(1-Pyridinio)-1-propanesulfonate can be used:
  • As a Bronsted acid ionic liquid catalyst in combination with H2SO4 and H3PO4 for the dehydration of glycerol to acrolein via semi-batch reaction technique.[1]
  • As a catalyst in the form of sulfonated heteropoly acid salts for the synthesis of isoamyl isovalerate.[2]
  • In the preparation of molybdenum imido alkylidene NHC catalysts, which are used in biphasic olefin metathesis.[3]
  • To prepare water-stable SO3H-functionalized Brønsted acidic task-specific ionic liquids (TSILs).[4]
