Succinic Anhydride is mainly used in the manufacture of polymeric materials (alkyd and other special resins). It is used in the manufacture of pharmaceuticals, agrochemicals, dyes, photographic chemicals, surface active agents, lubricant additives, organic flame retardant materials, esters, flavours and fragrances.

Application

In the laboratory, this material can be prepared by dehydration of succinic acid. Such dehydration can occur with the help of acetyl chloride or phosphoryl chloride, or thermally. Industrially, succinic anhydride is prepared by catalytic hydrogenation of maleic anhydride.
