Organic Chemistry in Medicine and Pharmaceuticals: Aspirin Synthesis
Objective:
Synthesize aspirin (acetylsalicylic acid) from salicylic acid and acetic anhydride.
Materials:
- 2.5 g salicylic acid
- 5 mL acetic anhydride
- 2 mL concentrated sulfuric acid
- Ice bath
- Graduated cylinder
- Erlenmeyer flask
- Condenser
- Round-bottom flask
- Filter paper
- Funnel
- Vacuum filtration apparatus
Procedure:
1. Weigh out 2.5 g of salicylic acid in a graduated cylinder and transfer it to an Erlenmeyer flask.
2. Add 5 mL of acetic anhydride to the flask.
3. Add 2 mL of concentrated sulfuric acid to the flask.
4. Connect the flask to a condenser and reflux for 30 minutes.
5. Cool the flask in an ice bath.
6. Filter the reaction mixture under vacuum.
7. Wash the filter paper with cold water.
8. Recrystallize the aspirin from hot ethanol.
Key Procedures:
- Reflux: This process involves heating the reaction mixture under a condenser, allowing the vapors to condense and return to the flask. This helps maintain a constant temperature and prevents the loss of volatile reagents.
- Vacuum Filtration: This technique uses a vacuum to pull a liquid mixture through a filter paper, separating the solids from the liquids.
- Recrystallization: This process purifies the synthesized aspirin by dissolving it in a solvent (ethanol) and allowing it to recrystallize.
Significance:
Aspirin is a widely used over-the-counter analgesic, anti-inflammatory, and antipyretic medication. It is synthesized through a process called esterification, which involves the reaction of a carboxylic acid (salicylic acid) with an alcohol or anhydride (acetic anhydride) to form an ester (aspirin). This experiment demonstrates the principles of organic chemistry and provides hands-on experience in the synthesis of a pharmaceutical drug.
