Experiment #6: Saponification of Wintergreen Oil 1.) Draw a reaction mechanism for the conversion of wintergreen oil into salicylic acid. 2. ) If you wanted to take an IR spectrum to confirm that the reaction worked, what would you look for in the spectrum? 3.) It is also possible to hydrolyze an ester under acidic conditions. Draw a mechanism for the acid-catalyzed conversion of wintergreen oil to salicylic acid.

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...

1. The actual substitution of the methoxy group in methyl salicylate with the hydroxyl group in salicylic acid requires one hydroxide ion, but in all actuality, a minimum of two equivalents of hydroxide ion are required for every one equivalent of the ester in order to achieve the theoretical yield. Explain why. 2.Why does the addition of sulfuric acid to the crude reaction mixture result in the precipitation of the product? Write a balanced reaction equation showing the chemistry that...
