and acetic anhydride; in the presence of sulfuric acid. After fully dissolving the salicylic acid with acetic anhydride‚ the solution is cooled and cold water is then added. Once the crystals form they are then filtered and left to dry out. There mass is measured and recorded then the yield is calculated. Introduction: Purpose: The aim of this experiment is to synthesize the common pain killer aspirin through an esterification reaction between Salicylic Acid and Acetic Anhydride; using sulfuric

polyvinyl acetate. Acetic anhydride Acetic anhydride can be synthesized by condensation reaction of two molecules of acetic acid. The main process involves dehydration of acetic acid to give ketene at 700-750 °C. Ketene is thereafter reacted with acetic acid to obtain the anhydride: CH3CO2H → CH2=C=O + H2O CH3CO2H + CH2=C=O → (CH3CO)2O Acetic anhydride is an acetylating agent. As such‚ its major application is for cellulose acetate‚ a synthetic textile. Acetic anhydride is also a reagent for the
