REACTION TYPE : Nucleophilic Substitution Reaction
PURPOSE : To prepare a Acetylsalicylic acid, more commonly known as aspirin. Aspirin is made by the reaction of salicyclic acid and acetic anhydride.
PRINCIPLE : 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.
MATERIALS USED :
Salicyclic Acid
Acetic Anhydride
Conc. H2SO4
Ethanol (Solvent)

please help
Mustrates treat all types of ilnesses. Background Aspirin is a prodrug of salicylic acid, the actual active drug. A compound related to salicylic acid, salicin, was first isolated from willow bark in the mid 1700's, but willow-bark extract was used by the andient Greeks as a treatment for pain and fever. Salicylic acid (and many related phenols) are very hard on your Ho stomach, but when esterified, as aspirin is, they are much better tolerated. Simple esters are...
