용도

Succinimide is used in organic syntheses and in industrial silver plating processes. It is a reagent that is used in the synthesis of Lumiflavin (L473900), which is a toxic photolysis product of vitamin B2 (R415000). Further, it is used to form covalent bonds between proteins, peptides and plastics. In addition to this, it is used as an important raw material for the synthesis of heterocyclic compounds through N-acyliminium cyclizations.

정의

ChEBI: Succinimide is a dicarboximide that is pyrrolidine which is substituted by oxo groups at positions 2 and 5. It is a pyrrolidinone and a dicarboximide.

제조 방법

To a flask equipped with a dropping funnel, mechanical stirrer, and a 40 cm long side arm of not less than 10 mm inside diameter is added 236 gm (2.0 mole) of succinic acid. The flask is cooled and 270 ml (4.0 moles) of 28% aqueous ammonia is slowly added with stirring. The flask is rapidly heated with an oil bath until 200 ml of water distils. The temperature of the bath is rapidly raised to 275°C. Succinimide starts to distil over the range 275-289°C, to afford 168 gm of crude product which solidifies on cooling. The intermediate fraction, boiling between 102° and 275°C, is redistilled to afford 10.0 gm of crude succinimide, b.p. 275-289°C. The combined product (178 gm) is added to 178 gm of hot ethanol. The solution is cooled, the crystals filtered, washed with 25 ml of cold ethanol, and dried to afford 163-164 gm (82-83%), m.p. 123-125°C. Approximately 4-5 gm of additional product may be obtained by concen­trating the mother liquor.
Recent Japanese patents suggested inert aprotic solvents such as cyclic amides (e.g., N-methylpyrrolidone, N-acetyl-2-pyrrolidone, DMF, or tet-ramethylurea) and azeotroping solvents (e.g., toluene, 0-xylene, hexane, or pentane) or other high-boiling solvents (e.g., chlorobenzene or chlo-rotoluene) as dehydrating agents for the formation of imides from di­basic acids (e.g., 3- and/or 4) hydroxyphthalic acid with a large variety of diamines including diaminosiloxanes such as bis (3-aminopropyl)-tetra-methylsiloxane.

Purification Methods

Crystallise the imide from EtOH (1mL/g) or water. [Beilstein 21 H 369, 21/9 V 438.]
