* | * 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. Nylon filter paper was used to collect the crystals. The filter paper is massed to be 0.0708 grams. | |||
*10. The mixture was run through a vacuum filtration setup. | |||
*11. The mass of the filter paper plus compound is 1.1461g Edited by [[User:Matt Hartings|Matt Hartings]] | |||
