October 3 rd , 2007 Craig Nutter Section #9 Wednesday 2:30pm Experiment 3 Title: Analysis and separation of components of an unknown drug Objective: To isolate substances in an unknown mixture and to determine the identity of these substances based on their melting point. Reactions: Reaction Table: Starting Material Amount Needed Isolation of 1 st compound Dicholormethane 8 mL Unknown Solvent 5 mL Extracting dicholor nitrate with 5% sodium bicarbonate Sodium Bicarbonate 12.5 mL Acetone 3 mL Isolate Compound in Vial B H2O 10 mL Isolate compound in Vial C 6M HCl 12 drops – 1.5 mL Boiling Stone 1 Results/Observations: Procedure 1. 5 mL of dicholomethane was added into a measuring cylinder. 2. This was then transferred into the unknown vial with the sample drug. 3. This was then shaken vigorously for 2 minutes. 4. The dissolved solution was filtered with a vacuum mechanism. Observations Weight of empty vial A: 14.789. The solution became cloudy as unknown was dissolved in dichloromethane. The top layer separated quickly and

5. 1.5 mL of dicholormethane was added from the dispenser. 6. The filtrate was poured into a 30 mL separating funnel 7. 2.5 mL of 5% sodium bicarbonate solution was then added to the dicholormethane. 8. The gas produced in this reaction was vented three times. 9. The solution formed was let to stand until 2 layers had formed. 10. The bottom layer was drained through the spout. 11. The top layer was then transferred to a different vial. 12. This process was repeated 2.5 mL of 3% sodium bicarbonate. 13. 3 mL of acetone was added to the original vial to dissolve the non- solubles in the dicholormethane. 14. These resultants were then added to the components in Vial A. 15. This mixture was then left to air dry.
