Itaconic anhydride is an important derivative of itaconic acid and a fine chemical raw material. Due to the presence of carbon carbon unsaturated double bonds and anhydride groups in its molecules, it has become an important polymer monomer in the production of polymer materials. It is widely used in the production of synthetic resins, synthetic fibers, ion exchange resins, surfactants, boiler cleaning agents, lubricating additives, adhesives, non-toxic packaging materials Raw materials or additives for herbicides and insecticides. The production methods of itaconic anhydride mainly include high-temperature (up to 120 ºC) dehydration and cyclization processes using methane sulfonic acid, xylene, phosphorus pentoxide, and other catalysts, as well as exchange dehydration and cyclization processes between itaconic acid and acetic anhydride.
