esophagus‚ and stomach. 2 These harsh qualities are alleviated by replacing the acidic hydrogens with less reactive groups of atoms: the acetyl group (COCH3). This results in acetylsalicylic acid or "aspirin". Acetylsalicylic acid is synthesized in labs and does not occur naturally. It is produced from adding acetic anhydride to salicylic acid in the presence of sulfuric acid (H2SO4)‚ an acid catalyst: (Diagram from 1) The impurities left over (unreacted salicylic acid‚ acetic acid and sulfuric acid)
