The reaction yield for the synthesis of aspirin is often lower than the theoretical yield partly because of product losses durin purification by re-crystallization. If the percent yield of the synthesis is only 40.%, how many grams of salicylic acid (MM = 138.1) must be used to obtain 50. g aspirin (MM = 180.2)? 1 Answer: COOH OH (C7H6O3) Salicyclic acid (s) + 0 CH3-C-0-C-CH3 (C4H603) Acetic anhydride (6) COOH 0 (CgHgO,) Aspirin (s) OCCH3 O + CH3COOH (C₂H₂O₂) Acetic acid ()

The reaction yield for the synthesis of aspirin is often lower than the theoretical yield partly because of product losses during purification by re-crystallization. If the percent yield of the synthesis is only 40.%, how many grams of salicylic acid (MM = 138.1) must be used to obtain 50. g aspirin (MM = 180.2)? Answer: COOH Jump to OH (C₂H6O3) Salicyclic acid (s) + CH3 010 C (CgHgO,) Aspirin (s) COOH 0 OCCH3 T 0 010 (C₂H603) Acetic anhydride () -CH3 + CH3COOH (C₂H4O₂) Acetic acid (E).
