一般描述
Phthalic anhydride is an industrially important chemical. It can be prepared from o-xylene or naphthalene. It is widely used for the industrial preparation of plasticizers for PVC (polyvinyl chloride).
Phthalic anhydride can be synthesized via oxidation of o-xylene, in the presence of V2O5/TiO2 monolithic catalyst supported by aluminium honeycomb.

应用
Phthalic anhydride may be used in the synthesis of the following compounds:
- pthalimide
- phenolphthalein
- anthracene

A rapid and sensitive electrophoretically mediated microanalysis method with field-enhanced sample injection (FESI) for in-capillary derivatization was developed to determine selenomethionine (SeMet) and selenomethionine selenoxide (SeOMet). Phthalic anhydride (PA) was selected as the derivatization reagent due to the fast reaction

An intermolecular nickel-catalyzed addition reaction has been developed where phthalic anhydrides react with alkynes to afford substituted isocoumarins. A mechanistic rationale is proposed, implying reductive elimination of Ni(0) promoted by ZnCl(2) cocatalyst as the key step of the catalytic cycle.
