Description

Maleic acid, also known as maleinic acid and toxilic acid, is a white crystalline (monoclinic) powder and possesses a faint acidulous odor and an astringent taste. It is soluble in water and alcohol. Maleic acid and fumaric 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.
