PREPARATION OF PHARMACEUTICALS - Fischer Esterification Reactions Q: Calculate the expected mass of both methyl salicylate and aspirin assuming 100% yield. EXPERIMENT7 PREPARATION OF PHARMACEUTICALS Fischer Esterification Reactions Almost 2500 years ago, physicians such as Hippocrates recommended that patients chew on the bark of the willow to alleviate pain. The active ingredient in willow bark was found to be salicin, a compound made of a molecule of salicyl alcohol bonded to a p-D-glucose molecule. In the stomach, the bond between...
