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 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.
