Application

1-Methylpyrrolidine is extensively used in the synthesis of pyrrolidine based ionic liquids. Some of the other reported applications include:
  • Synthesis of ionic liquid electrolytes for primary Li/CFx batteries.
  • Preparation of ionic liquid as a reaction medium to carry out sulfuric acid-catalyzed conversion of alkynes to ketones.
  • MCM-47, a highly crystalline ferrierite layered silicate, can be synthesized using a diquaternary ammonium salt prepared from the reaction of 1-methylpyrrolidine with 1,4-dibromobutane.
