Phthalic anhydride appears as a colorless to white lustrous solid in the form of needles with a mild distinctive odor. Moderately toxic by inhalation or ingestion and a skin irritant. Melting point 64°F Flash point 305°F. Forms a corrosive solution when mixed with water. Used in the manufacture of materials such as artificial resins.
Phthalic anhydride is the cyclic dicarboxylic anhydride that is the anhydride of phthalic acid. It has a role as an allergen. It is a cyclic dicarboxylic anhydride and a member of 2-benzofurans.
Phthalic anhydride is one of the most important organic chemical raw materials. Its main derivatives are dibutyl phthalate, dioctyl phthalate and diisobutyl acrylate. It is used as a plasticizer for PVC; it can also be used to produce unsaturated poly Ester resin, alkyd resin, dyes and pigments, various paints, food additives, laxatives in medicine, phenolphthalein, imipenem in pesticides, bentazone and sodium saccharin. Used as an analytical reagent and also for organic synthesis.
