Maleic acid is a linear four-carbon molecule with carboxylate groups on both ends and a double bond between the central carbon atoms. The anhydride of maleic acid is a cyclic molecule containing five atoms. Although the reactivity of mal eic anhydride is similar to other cyclic anhydrides, the products of maleylation are much more unstable toward hydrolysis, and the site of unsaturation lends itself to additional side-reactions.
Application:
Maleic acid is mainly used to produce unsaturated polyester resin, pesticide, tartaric acid, fumaric acid succinic acid, DL-malic acid, dyeing auxiliary and preservative grease. Maleic acid is also widely used in food and pharmaceutical industries.
