The chemical equation for the synthesis of aspirin is c7h6o3 + c4h6o3 – c9h8o4 +c2h4o2, which is a reaction of salicylic acid with acetic anhydride in the presence of phosphoric acid the byproduct is acetic acid adding cold water stops the reaction, and the products are filtered, yielding. Organic chemistry: in the synthesis of aspirin, why is salicylic acid treated with acetic anhydride instead of a regular carboxylic acid. Synthesis of aspirin from salicylic acid occurs by acetylation process in acidic medium salicylic acid interacts with acetic anhydride in presence of few drops of concentrated sulphuric acid to produce aspirin and a molecule of acetic acid.
