Quaternary Ammonium Salt Purification

  1. Turn off the heat on the round bottom flask containing the reaction and remove from the heating mantle.
  2. Fill a beaker with 100 mL ethyl acetate.
  3. Place on ice.
  4. Add the product drop-wise
  5. Filter and collect precipitate
  6. reaction failed was unable to purify. will discuss on monday as to other way to attach a quaternary ammonium to pva with fox
  7. reaction failed most likely due to the age of the starting material or decrease in strength of the leaving group Cl- compared to Br- for this reaction
