Phthalic anhydride is the organic compound with the formula C6H4
(CO)2O. This anhydride of
phthalic acid, a colourless solid, is an important industrial chemical, especially for the large-scale
production of plasticizers for plastics. In ***2, approximately 4.6 billion kilograms were produced
Applications in industry and organic synthesis.
Phthalic anhydride is a versatile intermediate in organic chemistry, in part because it is
bifunctional and cheaply available. It undergoes hydrolysis and alcoholysis. Hydrolysis by hot
water forms ortho-
phthalic acid. This process is reversible: Phthalic anhydride re-
forms upon
heating the acid above **0 °C.
Phthalic anhydride is widely used in industry for the production of certain dyes. A well-known
application of this reactivity is the preparation of the anthroquinone dye quinizarin by reaction
with para-chlorophenol followed by hydrolysis of the chloride.
