1. Mainly used in the production of plastic plasticizer, alkyd resin, dye, unsaturated resin and some pesticide.
2. Applications in industry and organic synthesis.
3. Hydrolysis of anhydrides is not typically a reversible process. However, phthalic acid is easily dehydrated to form phthalic anhydride due to the creation of a thermodynamically favorable 5-membered ring.
4. Widely used in industry for the production of certain dyes.
