Itaconic anhydride is the cyclic anhydride of itaconic acid (an unsaturated, dicarboxylic acid) and is obtained by the pyrolysis of citric acid. It is a colourless, crystalline solid, which dissolves in many polar organic solvents and hydrolyzes forming itaconic acid. Itaconic anhydride and its derivative itaconic acid have been promoted as biobased "platform chemicals" and bio- building blocks. ) Th…
