Citraconic anhydride Chemical Properties,Usage,Production

Chemical Properties

clear colorless to very slightly yellow liquid

Uses

Reagent for alkalies, alcohols, and amines.

Uses

Citraconic anhydride is used as a monomer for specialty unsaturated polyester resins. It is used to prepare bicyclic pyrrolidines, maleimides and co- and terpolymers. It is also used for the protection of N-terminal amino acids. Further, it is involved in the preparation of clothing ping acid and its amide. In addition to this, it is selectively used for the isolation of histidyl peptides.

Uses

Versatile reagent used for the synthesis of maleimides, bicyclic pyrrolidines, and co- and terpolymers, as well as for the protection of N-terminal amino acids.

Flammability and Explosibility

Non flammable

Purification Methods

Possible contamination is from the acid formed by hydrolysis. If the IR has OH bands, then reflux with Ac2O for 30minutes, evaporate, then distil the residue in a vacuum, otherwise distil in a vacuum. Store in a dry atmosphere.
