Acetaminophen Abstract: The aim of this experiment is to prepare Acetaminophen (p-acetamidophenol)‚ an amide. Acetaminophen will be created by treating an amine (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

THE PURITY AND PURIFICATION OF SOLIDS MELTING POINTS ABSTRACT Melting points of different mixtures of naphthalene and biphenyl were examined in this lab. Samples of these various mixtures were collected and tested by different individuals in the lab in order to find the eutectic point of biphenyl. Unknown substances were then tested using the mixture melting point method in order to determine their identities. INTRODUCTION The melting point of a solid is the temperature where the substance
