Acetyl-Salicylic Acid
(Aspirin)

, Synthesis In Laboratory
Principles –
2-Hydroxybenzoic acid reacts with an excess of ethanoic anhydride, in the presence of phosphoric ac
catalyst at 80 degrees for thirty minutes.
Acetic acid is produced as a byproduct.
Ethanoic anhydride is used in excess to ensure all salicylic acid is used up and reacts for maximum ov
yield.




The limited and small-sized equipment in laboratories, means that all kinds of synthesis of a product
conducted on a small scale. Therefore, measured more in grams and kilograms, rather than higher w
measurements.
