Phthalic Anhydride (PA)
White scaly or Crystalline powder, Molecular formula C8H403, Molecular weight 148.12, Melting point 131.1l , Boiling point 284.5 , Flash point 151 (close), 165 (open), Spontaneous combustion point 584 , Density (Solid) 1.527g / cm3, insoluble in water, soluble in water, alcohol, ether, benzene and most organic solvents. Phthalic anhydride is a cyclic anhydride, is an important chemical raw material, especially for plasticizer manufacturing. Dibutyl phthalate, Dioctyl phthalate are important plasticizers. Phthalic anhydride and polyols (such as glycerol, pentaerythritol) can generate polyarylate resin in condensation way, used in paint industry; if an unsaturated acid with ethylene glycol happening condensation, the resulting chemicals is unsaturated polyester resin, for the manufacturing of insulating paint and glass fiber reinforced plastics . Phthalic anhydride is a raw material of benzoic acid, terephthalic acid, also used in pharmaceutical synthesis.

Phthalic anhydride is the organic compound with the formula C6H4 (CO)2O. It is the anhydride of phthalic acid. This colourless solid is an important industrial chemical, especially for the large-scale production of plasticizers for plastics. Phthalic anhydride is an important chemical intermediate in the plastics industry from which are derived numerous phthalate esters that function as plasticizers in synthetic resins. Phthalic anhydride itself is used as a monomer for synthetic resins such as glyptal, the alkyd resins, and the polyester resins. Phthalic anhydride is also used as a precursor of anthraquinone, phthalein, rhodamine, phthalocyanine, fluorescein, and xanthene dyes. Phthalic anhydride is used in the synthesis of primary amines, the agricultural fungicide phaltan, and thalidomide. Other reactions with phthalic anhydride yield phenolphthalein, benzoic acid, phthalylsulfathiazole (an intestinal antimicrobial agent), and orthophthalic acid.
Phthalic anhydride is used in the manufacture of unsaturated polyesters and as a curing agent for epoxy resins. When used as a pigment, it can be responsible for sensitization in ceramic workers.n
Phthalic anhydride (PA) is a white crystalline compound used to manufacture
plasticizers, pigments, dyes and resins. One major consumer of PA is the
phthalate plasticiser industry, the products of which are used to produce
flexible plastic products such as wire & cable applications, hoses, pipes,
coated fabrics, roofing membranes and swimming pool liners.

Phthalic anhydride (PA) is a white crystalline compound used to manufacture plasticizers, pigments, dyes and resins.
PA is used in the manufacture of unsaturated polyester resins (UPR) that are usually blended with glass fibers to produce fiberglass-reinforced plastics. Principal consumer markets are the construction, marine, and transportation sectors. PA-based alkyd resins are used in paints and lacquers that go in to architectural, machinery, furniture, and fixture applications.
