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 orthophthalic acid. 
This process is reversible: Phthalic anhydride reforms upon heating the acid above 180°C.
