Phthalic anhydride is a white solid and is an important raw material in chemical industry, especially for the manufacture of plasticizers. important plasticizer. Used in the paint industry; production of unsaturated polyester resins for the manufacture of insulating varnishes and glass fiber reinforced plastics, also for pharmaceutical synthesis.
Phthalic anhydride is widely used worldwide for an extremely broad range of applications spanning from the plastics industry to the synthesis of resins, agricultural fungicides and amines. Its production is currently based on the vapor phase oxidation of o-xylene and naphthalene.
