Description

Phthalic anhydride is a white solid organic compound with the formula C8H4O3. It is the anhydride of phthalic acid. It is an important industrial chemical used in the production of plasticizers, resins, and dyes. It is synthesized by the catalytic oxidation of ortho-xylene or naphthalene with air. Phthalic anhydride is a versatile chemical intermediate and is used in the production of many other chemicals. For example, it is used to make phthalates, which are used as plasticizers to make plastics more flexible. Phthalic anhydride is also used in the production of alkyd resins, which are used in paints and coatings. It is also a starting material for the synthesis of many other chemicals, including dyes, pharmaceuticals, and pesticides. Phthalic anhydride is an important industrial chemical and is studied extensively for its applications in many different industries.'
