Itaconic anhydride
Chemical compound / From Wikipedia, the free encyclopedia
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.[4] Itaconic anhydride and its derivative itaconic acid have been promoted as biobased "platform chemicals" and bio- building blocks.[5][6]) These expectations, however, have not been fulfilled.[7]
