Chemical Properties

WHITE TO CREAM CRYSTALLINE POWDER

Purification Methods

Crystallise the anhydride from CHCl3/pet ether. It can be distilled under reduced pressure. Distillation at atmospheric pressure, or prolonged distillation causes rearrangement to citraconic anhydride (2-methylmaleic anhydride). If the material (as seen in the IR spectrum) contains much free acid, then heat with acetyl chloride or SOCl2, evaporate and distil at as high a vacuum as possible. The crude anhydride deposits crystals of itaconic acid on standing probably due to hydrolysis by H2O — store it in sealed ampoules under dry N2. [Skinner et al.
