Phthalic Anhydride (naphthalene) is produced by catalytic oxidation of naphthalene. As the anhydride of phthalic acid, phthalic anhydride is a toxic, white crystalline compound. Because of it’s bifunctional and readily available, PA is an important industrial chemical, especially for the large–scale production of plasticizers for plastics.
