[PDF] 8-Synthesis of Aspirin

Aspirin can be made by reacting salicylic acid with acetic acid in the presence of an acid catalyst If acetic anhydride is used instead of acetic acid, the reaction is much faster and has a higher yield (since acetic anhydride is much more reactive than acetic acid) The reaction is shown on the following page
