Maleic Anhydride (MA) is used as a chemical intermediate in the synthesis of fumaric and tartaric acid, certain agricultural chemicals, resins in numerous products, dye intermediates, and pharmaceuticals (HSDB, 1995).
MA is largely used in the production of unsaturated polyester resins. These resins are used primarily in fiber-reinforced plastics; materials with a wide and growing range of applications in boating, automobile and construction industries. It is also used as a co-monomer for unsaturated polyester resins, an ingredient in bonding agents used to manufacture plywood, a corrosion inhibitor, and a preservative in oils and fats.
MA is used in the manufacture of alkyd resins, which are in turn used in paints and coatings. Other applications where maleic anhydride is used include the production of agricultural chemicals, malic acid, copolymers, fumaric acid, lubricant additives, surfactants and plasticizers. A lesser known use for MA is lubricating oil additives.
