Pure Polyisobutylene Succinic Anhydride

we are indulged in exporting, supplying and trading of polyisobutylene succinic anhydride in Mumbai, Maharashtra, India. Succinic anhydride, is an organic compound with the molecular formula (CH2CO)2O. This colorless solid is the acid anhydride of succinic acid. 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, or thermally.

Industrially, succinic anhydride is prepared by catalytic hydrogenation of maleic anhydride.

Maleic anhydride undergoes the Alder-ene reaction with olefins to give alkenylsuccinic anhydrides. Such compounds are sizing agents in the paper industry. In this role, the anhydride is proposed to form an ester with the hydroxyl groups on the cellulose fibers. Maleic anhydride undergoes a similar reaction with polyisobutylene to give polyisobutylenylsuccinic anhydride, a common building block chemical in the petroleum additives industry.
