Description of Tetrahydrophthalic anhydride(THPA)

Phthalic anhydride, the anhydride form of phthalic acid , is produced by the oxidation of orthoxylene and naphthalene. 

Its wide application is based on the ortho related carboxylic acid groups as their dehydration is highly reactive with broad 

processing conditions to produce various downstream products. It is used to make simple esters widely used as plasticizers. 

It is used as in making unsaturated polyester resins, alkyd resins, polyester polyols, dyes and pigments, halogenated anhydrides, 

polyetherimide resins, isatoic anhydride and insect repellents.Anhydride is a compound formed by the abstraction of a m

olecule of water, H2O, from a substance. The term acid anhydride is restricted sometime to the anhydride formed especially 

from an acid by dehydration or one that revert to the original substance upon hydration. In case of bimolecular, it can be c

omposed of two molecules of the corresponding acid. The term mixed anhydride is an acid anhydride composed of two different a

cids. Examples are adenosine triphosphate or an aminoacyl adenylate. The anhydrides of bases are oxides.
