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.
Phthalic anhydride may be used in the synthesis of the following compounds:
1 kg in poly bottle
2.5 kg in poly drum
16 kg in fiber drum
