If acetic anhydride is used instead of acetic acid, the reaction is much faster and has a The collected aspirin will be tested for its purity using FeCl3 (aq)
Synthesis of Aspirin
To prepare aspirin, salicylic acid is reacted with an excess of acetic A “purified product” can be obtained through acetic anhydride from a buret into the flask
