AP Chemsirty Synthesis of Aspirin Classroom Kit
by Innovating Science

This experiment will take you through the process of synthesizing acetylsalicylic acid, also known as aspirin, purifying it through recrystalization, and then using the melting point to confirm its identity.

This method of synthesizing aspirin was developed by Felix Hoffman, and involves the acetylation of salicylic acid by means of acetic anhydride. When the salicylic acid is mixed with acetic anhydride and sulfuric acid, they produce an exothermic reaction that causes the temperature of the solution to increase to approximately 70-80C. When the reaction has stopped and then been put into an ice back, the acetylsalicylic acid will begin to crystalize out of the solution, and can be recrystalised with toluene in an effort to purify the product. By using the melting point, we can confirm that the product is acetylsalicylic acid, and then use the re-crystalized aspirin to determine the yield.

This kit includes enough material to be conducted by approximately 15 groups:

  • 2x 25mL of Acetic anhydride
  • 2x 25mL of Sulfuric acid
  • 2x 25mL of Toluene
  • 15g of Salicylic acid

Each bottle of our reagents come standard with an MSDS sheet included. If you require a copy of this prior to purchase, please contact us.

Not included in this kit, but required, is a micro organic chemistry set.
