What is the difference between acetylsalicylic acid and salicylic acid?
Salicylic acid has long been a key starting material for making acetylsalicylic acid (aspirin). Aspirin (acetylsalicylic acid or ASA) is prepared by the esterification of the phenolic hydroxyl group of salicylic acid with the acetyl group from acetic anhydride or acetyl chloride.
How do you find the mass of aspirin in a sample?
4. Answers will vary. For the sample data, the mass of synthesized aspirin is 1.96 g. Corrected for purity, is: (1.96 × 0.75) = 1.47 g. The percent yield is: (1.47 g ÷ 2.63 g) × 100 = 55.9%….Part I Synthesis of Aspirin.
