Product Description

Product Description

Phthalic anhydride, or phthalic anhydride, is a cyclic anhydride formed by the intermolecular dehydration of phthalic acid. Benzyl anhydride is a white solid, which is an important raw material in chemical industry, especially in the manufacture of plasticizer. Phthalate anhydride can be used instead of phthalic acid and mainly reacts with monoalcohols to form esters, such as dibutyl phthalate and dioctyl phthalate.
