Anwendungen

Phthalic acid is used as an active ingredient in polyesters and alkyd resins. It is also used as plasticizers for polyvinyl chloride and other polymers. It is also useful in the production of anthraquinone, phenolphthalein and phthalocyanine pigments. It serves as an organic reagent in the production of phthalates. It is used to prepare 1,3-cyclohexadiene by reduction using sodium amalgam.

Bemerkungen

Incompatible with strong oxidizing agents.
