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

Homogeneous modification of cellulose, isolated with 10% KOH from delignified sugarcane bagasse, was performed in room-temperature ionic liquid 1-allyl-3-methylinidazolium chloride with phthalic anhydride in the absence of catalyst. The results showed the degree of substitution of phthalated cellulosic derivatives, ranging
