SUCCINIC ANHYDRIDE FOR SYNTHESIS
SUCCINIC ANHYDRIDE FOR SYNTHESIS
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.
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.
Succinic anhydride appears as colorless needles or white crystalline solid. Melting point 237°F. Sublimes at 239°F at 5 mm Hg pressure; and at 198°F and 1 mm Hg pressure. Moderately toxic and an irritant.
Succinic anhydride, is an organic compound with the molecular formula (CH2CO)2O. This colorless solid is the acid anhydride of succinic acid.
