A big problem with phosphoric acid is that the most concentrated you can normally get is 85%, which means you still have to remove 15% of water somehow. If you don't, you'll likely hydrolyse any aspirin formed and get your starting material back. Share.

WebSynthesis of Aspirin Aspirin is the single most manufactured drug in the world. Aspirin’s chemical name is acetylsalicylic acid, and it is synthesized from the reaction of acetic anhydride with salicylic acid in the presence of phos-phoric acid as a catalyst. The by-product is acetic acid (Figure 5.1). http://images.pcmac.org/SiSFiles/Schools/AL/TallasseeCitySchools/TallasseeHigh/Uploads/DocumentsCategories/Documents/Aspirin_Synthesis_-_Student_(PDF).pdf

WebThe Chemistry of Aspirin (acetylsalicylic acid) Chemical formula = C9H8O4 or CH3COOC6H4COOH or HC9H7O4 Aspirin is prepared by chemical synthesis from salicylic acid, through acetylation with acetic anhydride.
