Succinic anhydride, also called dihydro-2,5-furandione and butanedioic anhydride , is an organic compound with the molecular formula C4H4O3. This colorless solid is the acid anhydride of succinic acid.
Preparation
In the laboratory, this material can be prepared by dehydration of succinic acid. Such dehydration can occur with the aid of acetyl chloride or phosphoryl chloride,[4] or thermally.[5]
Industrially, succinic anhydride is prepared by catalytic hydrogenation of maleic anhydride.[5]
Related compounds
Maleic anhydride undergoes the Alder-ene reaction with olefins to give alkenyl succinic anhydrides that are sizing agents in the paper industry. It undergoes a similar reaction with polyisobutylene to give polyisobutylenyl succinic anhydride, a common building block chemical.
