Phthalic anhydride is a white crystalline solid that is the commercial form of phthalic acid. Phthalic anhydride is an important compound derived from the oxidation reaction of naphthalene. On the basis of application areas, the market of phthalic anhydride can be broadly segmented into plasticizers, unsaturated polyester resins, alkyd resins, and others. Plasticizer is the main phthalic anhydride application and serves an array of industries due to its various properties and performance advantages.

Phthalic Anhydride is used to produce polyester polyols for a variety of Polyurethane markets and to make polyester resins for reinforced plastics. This versatile chemical is also used in the manufacture of alkyd resins for paints and protective coatings. Phthalic Anhydride is reacted with alcohols to produce phthalate ester plasticizers for synthetic resins and plastics. Other uses for Phthalic Anhydride include the making of dye intermediates, pigments, engineering plastics, benzoic acid and phenolphthalein.
