一般描述
Phthalic anhydride is an industrially important chemical. It can be prepared from o-xylene or naphthalene.[1] It is widely used for the industrial preparation of plasticizers for PVC (polyvinyl chloride).[2]
Phthalic anhydride can be synthesized via oxidation of o-xylene, in the presence of V2O5/TiO2 monolithic catalyst supported by aluminium honeycomb.[3]

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.

A new method for the analysis of alcohol ethoxylates (AEs) using electrospray ionisation liquid chromatography/mass spectrometry (ESI LC/MS) is described. The procedure incorporates a novel derivatisation step with phthalic anhydride for the analysis of EO0-20 ethoxylates in a single analysis.
