  • Description Maleic Anhydride (MAN) is an organic compound with the chemical formula C4H203. It is the acid anhydride of maleic acid and in its pure state it is a colourless or white solid with an acrid odour. Maleic anhydride is truly a remarkable molecule in that it possesses two types of chemical functionality making it uniquely useful in chemical synthesis and applications. Maleic Anhydride is a multifunctional chemical intermediate with applications in several fields of chemical industry. Its major end use is as feedstock in the production of unsaturated polyester resins (UPR). These resins are used both in glass-reinforced and in unreinforced applications. The UPR end uses includes a wide range of applications in construction, marine and automobile industries. In addition, Maleic Anhydride can also be used as raw material in the production of 1,4-butanediol (BDO), gamma- butyrolactone and tetrahydrofuran (THF). It is important to highlight that BDO is one of the world's fastest growing chemicals in the last years.
  • Physical properties White, hydroscopic crystals (usually shipped as briquettes). Odor threshold concentration is 0.32 ppm (quoted, Amoore and Hautala, 1983).
  • Uses In the manufacture of polyester resins, fumaric acid, agricultural pesticides, and alkyl resins Maleic Anhydride is heterocyclic compound used in the manufacture of unsaturated polyester resins. Maleic Anhydride has a wide range of other applications; it is used in synthetic tensides, insecticides, herbicides and fungicides. In Diels-Alder syntheses (as a dienophile), manufacture of alkyd-type of resins, dye intermediates, pharmaceuticals, agricultural chemicals (maleic hydrazide, malathion), in copolymerization reactions.
