Introduction:
Phthalic anhydride is the organic compound with the formula C8H4O3. This anhydride of phthalic acid,
a colourless solid, is an important industrial chemical, especially for the large-scale production of plasticizers for plastics. In 2002, approximately 4.6 billion kilograms were produced

Applications of phthalic anhydride
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 180℃.
