Experiment: Preparation of Aspirin (Acetylsalicylic Acid)

Objective: To synthesize aspirin, a common over-the-counter pain reliever, from salicylic acid and acetic anhydride.
Materials:
  • 5 grams salicylic acid
  • 10 mL acetic anhydride
  • 1 mL concentrated sulfuric acid
  • 100 mL distilled water
  • Ice bath
  • Erlenmeyer flask
  • Thermometer
  • Stirring rod
  • Büchner funnel (or filter paper and funnel)
Procedure:
  1. Preparing the Reaction Mixture:
    • Add 5 grams of salicylic acid and 10 mL of acetic anhydride to an Erlenmeyer flask.
    • Slowly add 1 mL of concentrated sulfuric acid to the mixture while stirring constantly.
    • Place the flask in an ice bath to maintain a temperature below 30°C during the reaction.
  2. Reaction:
    • Stir the reaction mixture continuously for about 30 minutes, or until the salicylic acid dissolves completely.
  3. Cooling and Crystallization:
    • Remove the flask from the ice bath and allow it to cool to room temperature.
    • Add 100 mL of distilled water to the reaction mixture and stir to dissolve any remaining solids.
    • Cool the solution in an ice bath again until crystals of aspirin start to form.
  4. Filtration and Drying:
    • Filter the crystallized aspirin using a Büchner funnel (or filter paper and funnel).
    • Wash the crystals thoroughly with cold water to remove any impurities.
    • Spread the crystals on a filter paper and allow them to dry completely.
Significance:
  • This experiment demonstrates the synthesis of a widely used pharmaceutical product, aspirin, through a simple organic reaction.
  • It highlights the importance of organic chemistry in the pharmaceutical industry and showcases the principles of organic synthesis.
  • The experiment also provides hands-on experience in handling and processing organic compounds, as well as techniques like crystallization, filtration, and drying.

Safety Precautions: Concentrated sulfuric acid is corrosive. Wear appropriate safety goggles and gloves. Perform the experiment in a well-ventilated area.
