It tastes sweet. Easily soluble in water, alcohol or sodium hydroxide solution, insoluble in ether, chloroform, etc. Succinimide dispersants appear as dark or brown-colored liquids with a thickness or viscosity similar to heavy syrup. They have little or no solubility in water, and because they are denser than water, will sink in a water environment. They are readily soluble in oil and lighter weight hydrocarbons, such as gasoline. Succinimide dispersants have very low vapor pressure and little noticeable odor at ambient temperatures. Chemical Properties white crystalline powder Uses Succinimide is a cycle imide of succinic acid that is present in numerous biologically active compounds including anticonvulsants, antitremor, anti-Parkinson's agents. Succinimide is the key intermediate for deamidation of asparagine (Asn) and isom-erization of aspartic acid (Asp) residues in a protein or peptide, either in vivo or invitro (Wakankar and Borchardt 2006). Formation of succinimide is the rate-deter-mining step in these reactions. Uses 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. Preparation 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. Definition 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.

Vol. 2, p. 562, 1943 Chemical Synthesis Succinimide is obtained by the reaction of succinic acid with ammonia. Succinic acid and water are added into the reaction pot, and succinimide can be produced by ammonia reaction. Succinic acid can also be put into the reaction pot, drop ammonia, stir to dissolve and react, heat it to 102 ℃, evaporate the water, and then carry out vacuum distillation. When the temperature rises to 180 ℃, start collecting succinimide fraction to obtain the finished product. Purification Methods Crystallise the imide from EtOH (1mL/g) or water.
