설명

일반 설명

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]

애플리케이션

Phthalic anhydride may be used in the synthesis of the following compounds:

• pthalimide[4]
• phenolphthalein[5]
• anthracene[6]
