Experiment: Synthesis of Aspirin
Introduction:
Aspirin is a widely used analgesic, antipyretic, and anti-inflammatory drug. It is also known as acetylsalicylic acid. Aspirin was first synthesized in 1897 by the German chemist Felix Hoffmann. It is one of the most commonly used drugs in the world.
Objective:
The objective of this experiment is to synthesize aspirin from salicylic acid and acetic anhydride. The synthesis of aspirin is a relatively simple organic chemistry reaction that can be performed in a laboratory setting. The experiment will demonstrate the key procedures involved in organic chemistry reactions, such as reflux, filtration, and recrystallization.
Materials:
- Salicylic acid
- Acetic anhydride
- Sulfuric acid
- Water
- Ice
- Beaker
- Condenser
- Filter paper
- Funnel
- Vacuum filtration flask
Procedure:
- In a beaker, add 5 g of salicylic acid and 10 mL of acetic anhydride.
- Add 2 drops of sulfuric acid to the mixture.
- Heat the mixture under reflux for 30 minutes.
- Cool the mixture in an ice bath.
- Filter the mixture using a vacuum filtration flask.
- Wash the crystals with water.
- Recrystallize the crystals from hot water.
Results:
The yield of aspirin was approximately 75%. The melting point of the aspirin crystals was 135-137 °C, which is consistent with the literature value. The IR spectrum of the aspirin crystals showed the characteristic peaks for the aspirin functional groups.
Discussion:
The synthesis of aspirin is a straightforward organic chemistry reaction that can be performed in a laboratory setting. The reaction involves the nucleophilic acyl substitution of salicylic acid with acetic anhydride. The sulfuric acid catalyst protonates the salicylic acid, making it more reactive towards nucleophilic attack. The aspirin crystals were recrystallized from hot water to purify them. The melting point of the aspirin crystals was consistent with the literature value, which indicates that the aspirin was successfully synthesized.
Significance:
The synthesis of aspirin is a significant experiment in organic chemistry because it demonstrates the key procedures involved in organic chemistry reactions. The experiment also highlights the importance of organic chemistry in medicine. Aspirin is one of the most widely used drugs in the world, and it is used to treat a variety of conditions, including pain, fever, and inflammation.
