It appears as white crystalline powder and is an important raw material in the field of organic chemicals, mainly used in the production of plasticizers. In practical applications, phthalic anhydride can be used as a substitute for phthalic acid and mainly reacts with monohydric alcohols to form esters, such as dibutyl phthalate and dioctyl phthalate. APPLICATIONPhthalic anhydride is an important organic chemical raw material and a key intermediate for the preparation of phthalate plasticizers, coatings, saccharin, dyes and organic compounds. It undergoes polycondensation with polyols (such as glycerol and pentaerythri-tol) to form polyarylate resins, which are used in the paint industry. When it undergoes polycondensation with ethylene glycol and unsaturated acids, it produces unsaturated polyester resins, which can be used to manufacture insulating paints and glass fiber-reinforced plastics. Phthalic anhydride is also a raw material for the synthesis of benzoic acid and terephthalic acid, and is applied in pharmaceut-ical synthesis as well.
