Maleic acid Usage And Synthesis
Description Maleic acid is an organic compound that is a dicarboxylic acid, a molecule with two carboxyl groups. Its chemical formula is HO2CCHCHCO2H. Maleic acid is the cis-isomer of butenedioic acid, where as fumaric acid is the trans-isomer. It is mainly used as a precursor to fumaric acid, and relative to its parent maleic anhydride, maleic acid has few applications.
Chemical Properties Maleic acid, HOOCCH:CHCOOH, also known as maleinic acid and toxilic acid,is a colorless crystalline dibasic acid. It is soluble in water and alcohol. Maleic acid is used in manufacturing synthetic resins, in textile processing, and in preserving oils and fats.
Chemical Properties Maleic acid is a white crystalline solid. Faint, acid like odor.
Chemical Properties Maleic acid occurs as a white crystalline (monoclinic) powder and possesses a faint acidulous odor and an astringent taste.
Fumaric acid and maleic acid are the simplest unsaturated carboxylic diacids. These acids experience two-step dissociation in aqueous solutions.They have the same structural formula but different spatial configurations. Fumaric acid is the trans and maleic acid the cis isomer. The physical properties of maleic acid and fumaric acid are very different. The cis isomer is less stable. Maleic acid is used in the preparation of fumaric acid by catalytic isomerization.
