Product Description

Product Description

 

Phthalic  anhydrid e, abbreviated as phthalic  anhydride, is a cyclic acid anhydride formed by dehydration of phthalic acid molecules. Phthalic  anhydride, a white solid, is an important raw material in the chemical industry, especially for the manufacture of plasticizers. Phthalic  anhydride can be used instead of phthalic acid, mainly reacting with mono alcohols to form esters, such as dibutyl phthalate, dioctyl phthalate.
