If acetic anhydride is used instead of acetic acid, the reaction is much faster Write out the balanced equation for the reaction between salicylic acid and acetic
Synthesis of Aspirin
To prepare aspirin, salicylic acid is reacted with an excess of acetic anhydride A small amount of a strong acid is used as a catalyst which speeds up the reaction
