(p-aminophenol) with an acetic anhydride. Color impurities present in the solid acetaminophen will be removed and then the decolorized product will be collected on a Büchner funnel for further purification by crystallization. Purity will then be determined by melting point. Introduction: Acetaminophen is commonly used as an analgesic to reduce pain and fever. In this experiment it is prepared by the reaction of p-aminophenol with acetic anhydride‚ as illustrated below. Results: Isolation of crude acetaminophen
