IPCS INCHEM - CYCLIC ACID ANHYDRIDES: HUMAN HEALTH ASPECTS

Local:
Succinic Anhydride is mainly used in the manufacture of polymeric materials (alkyd and other special resins). It is used in the manufacture of pharmaceuticals, agrochemicals, dyes, photographic chemicals, surface active agents, lubricant additives, organic flame retardant materials, esters, flavours and fragrances. Its application include as a cross-linking agent in ion-exchange membranes, curing agent for epoxy resins and starch modifier in foods and feeds.

GENERAL DESCRIPTION OF SUCCINIC ACID: Succinic Acid (also called Butanedioic Acid) is a dicarboxylic acid with four carbon atoms, occurring naturally plant and animal tissues and that plays a significant role in intermediary metabolism (Krebs cycle). It is a colourless crystalline solid with a melting point of 185-187º C, soluble in water, slightly dissolved in ethanol, ether, acetone and glycerine, but not dissolved in benzene, carbon sulfide, carbon tetrachloride and oil ether. The common method of synthesis of succinic acid is the catalytic hydrogenation of maleic acid or its anhydride. Succinic acid has uses in certain drug compounds, in agricultural and food production, and in perfume esters manufacturing.

Dicarboxylic acid is a compound containing two carboxylic acid, -COOH, groups. Examples are shown in table. In substitutive nomenclature their names are formed by adding -dioic' as a suffix to the name of the parent compound. They can yield two kinds of salts, as they contain two carboxyl groups in its molecules.
