Synthesis of Acetaminophen Postlab Questions During the crystallization of acetaminophen, why was the mixture cooled in an ice bath? 1. In the reaction between p-aminophenol and acetic anhydride to form acetaminophen, 0.450 mL of water was added. What was the purpose of the water? 2. Why should you use a minimum amount of water to rinse the conical vial while transferring the purified acetaminophen to the Hirsch funnel? 3. If 0.130 g of p-aminophenol is allowed to react with excess...
