  • The same reaction will be run as last week, except with 250 mg of Protoporyphrin IX and 115 mg of Nickelous Sulfate.
  • The same procedure will be followed.


  • 1. 250 mg Protoporyphrin IX and 115 mg Nickelous Sulfate was measured out on a balance
  • 2. 25 mL DMF is added to a 50mL Round-Bottom flask with a 19/22 opening
  • 3.. The flask was placed on a heating pad with a 100 Volt Volt-ac with a stir bar under the presence of Nitrogen.
  • 4. The DMF was brought to reflux under these conditions (1).
  • 5. Once the DMF was in reflux, the protoporphyrin IX was added, and let reflux (1).
  • 6. The Nickelous Sulfate was then added, and let reflux for 30 minutes (1).
  • 7. The flask was then chilled in an ice bath for 15 minutes (1).
  • 8. 250 mL of chilled water was then added, was left to chill for 10 minutes, and the precipitate is filtered using a Buchner funnel (1).
  • 9. The filtered material was washed with water (1).
