Description
Maleic Anhydride is an organic compound in the form of white crystalline flakes or a solid with an acrid odor. It is produced by the oxidation of benzene or butane and serves as a key raw material in the production of unsaturated polyester resins, lubricating oil additives, agricultural chemicals, and fumaric acid. Due to its high reactivity, it is widely used in the chemical industry for various polymerization and esterification reactions.
