C8H4O3
Phthalic Anhydride
Exclusive Features
- Phthalic anhydride is a versatile intermediate in organic chemistry, in part because it is bifunctional and readily available
- Phthalic anhydride is the anhydride of phthalic acid. This colorless solid is an important industrial chemical, especially for the large–scale production of plasticizers for plastics
Applications
Major Consuming Industries
- Chemical intermediate in the production of plastics from vinyl chloride
- Production of polyester resins
- Production of alkyd resins used in paints and lacquers, certain guys, insect repellents, and urethane polyester polyols
- Used as a rubber scorch inhibitor and retarder
