Applications

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.
