Succinic Acid


HOOCCH2CH2 COOH. Also known as butanedioic acid, succinic acid is a colorless, crystalline compound that is soluble in ethanol, ether, and water.

Succinic acid has a melting point of 185°C and a density of 1.563 g/cm3 at 20°C. It is found in small amounts in brown coal, amber, plants, and animals; it is an intermediate in the tricarboxylic acid cycle.

Succinic acid is produced industrially mainly by the hydrogenation of maleic anhydride. The acid itself and a number of its derivatives—including its anhydride, monoamides, diamides, and esters and salts (succinates), as well as succinimide—are used in the production of various plastics, polyester resins, dyes, insecticides, and pharmaceuticals; they are also used in the synthesis of polynuclear aromatic hydrocarbons.
