itaconic acid [¦id·ə¦kän·ik ′as·əd]
(organic chemistry) CH2:C(COOH)CH2COOH A colorless crystalline compound that decomposes at 165°C, prepared by fermentation withAspergillus terreus;used as an intermediate in organic synthesis and in resins and plasticizers. Itaconic Acid an unsaturated dibasic carboxylic acid, H2C=C(COOH)—CH2COOH; colorless crystals. Melting point, 167°-168°C. Itaconic acid yields chloranhydride on heating with thionyl chloride; it yields esters upon interaction with alcohols. It combines with halogens and hydrogen halides in a double bond and readily polymerizes during storage (hydroquinone can be used as an inhibitor). Itaconic acid is used in the manufacture of synthetic detergents; its esters are used in the production of copolymers with methacrylates and styrene, and as polyvinylchloride plasticizers.
