This agent exhibits analgesic, antipyretic, and anticoagulant properties.
The chemical reaction yields aspirin and acetic acid.
How is acetylsalicylic acid used as a catalyst?
Salicylic acid acting as an alcohol is reacted with acetic anhydride acting as the acid in an esterification reaction to produce an ester, acetylsalicylic acid (aspirin). Concentrated sulfuric acid is used as a catalyst. Limiting Reagent and % Yield:
How is acetylsalicylic acid ( aspirin ) synthesized?
Synthesis of Acetylsalicylic Acid Aspirin is synthesized by the action of salicylic acid on acetic anhydride. It is an esterification reaction. In this reaction, when salicylic acid reacts with acetic anhydride, the hydroxyl group of salicylic acid converts into an ester group.
What are the side effects of acetylsalicylic acid?
It has various side effects as well such as high dose may result in the ringing of ears, Reye syndrome, nausea, upset stomach, headache etc. Acetylsalicylic acid was first produced by Alsatian Chemist Charles Frederic Gerhardt in 1853 from sodium salicylate and acetyl chloride.
How are acetic anhydride and salicylic acid mixed?
This was be accomplished through the use of recrystallization. Acetic anhydride and salicylic acid are mixed together, and then acidified by the addition of a few drops of concentrated sulfuric acid, which catalyzed the reaction.
