| | Succinic anhydride Usage And Synthesis |
| Description | Succinic anhydride, also called di hydro - 2,5- furandione , is an organic compound with the molecular formula C4H4O3.This colorless solid is the acid anhydride of succinic acid. | | Chemical Properties | fine white crystalline solid | | Chemical Properties | Succinic anhydride is an odourless, colourless needle-like or white crystalline solid natural product. Molecular formula C4H4O3, molecular weight 100.07 g/mol, relative density 1.503, melting point 237 °F. 239 °F at 5 mmHg, 239 °F at 198 °F and 1 mmHg. Soluble in chloroform, carbon tetrachloride, and ethanol; very slightly soluble in ether and water (insoluble in water). Moderately toxic and irritating, emits pungent and irritating fumes when heated to decomposition. | | Uses | Succinic Anhydride is an acidulant that hydrolyzes very slowly to
succinic acid in water. it has thermal stability and a low melting
point of 118°c which permits it to be used in products at compara-
tively low temperatures. it is used as a leavening acidulant for bak-
ing powder. | | Uses | It was used in the preparation of covalently cross-linked oxidized-alginate/N-succinyl-chitosan hydrogels, as injectable systems towards tissue engineering.It was also used in preparing functionalized oxide surfaces on a chip. | | Uses | Succinic Anhydride is a useful compound in the paper manufacturing process. | | Preparation | A solution of succinic acid (500 mg, 42 mmol) and triethylamine (1.23 mL, 42 mmol) in anhydrous THF (120 mL) was allowed to react with triphosgene (42 mg, 7.0 mmol) at ice-water temperature for 10 min. The reaction mixture was subsequently stirred for a further 15 min at room temperature. The solution was then filtered, and the filtrate was concentrated to dryness. The residue was crystallized from ethyl acetate to afford the desired product as white crystals (370 mg, 85%). | | Production Methods | The compound is produced from succinic anhydride and
hydrogen peroxide . This material must be stabilized by
using a dehydrating agent such as disodium sulfate or
magnesium sulfate. | | Application | Alkyl succinic anhydride (ASA) is used as a sizing agent or wet strength additive in paper production. | | Definition | ChEBI: Succinic anhydride is a cyclic dicarboxylic anhydride and a tetrahydrofurandione. It is functionally related to a succinic acid. | | Synthesis Reference(s) | Synthetic Communications, 23, p. 419, 1993 DOI: 10.1080/00397919308009796 | | General Description | Succinic anhydride is a cyclic anhydride of succinic acid with a five-membered ring. It is widely used in the manufacture of polymeric materials, pharmaceuticals, agrochemicals, dyes, surface-active agents, and organic flame-retardant materials. It also finds application as a cross-linking agent in ion-exchange membranes and a curing agent for epoxy resins. | | General Description | 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. | | Air & Water Reactions | Reacts slowly with water. Insoluble in water. | | Reactivity Profile | Succinic anhydride reacts exothermically with water. Reactions are usually slow, but might become violent if local heating accelerates their rate. Acids accelerate the reaction with water. Incompatible with acids, strong oxidizing agents, alcohols, amines, and bases. | | Fire Hazard | Flash point data for Succinic anhydride are not available, however, Succinic anhydride is probably combustible. | | Flammability and Explosibility | Not classified | | Materials Uses | Succinic anhydride can be used:
(1) In the preparation of covalently cross-linked oxidized-alginate/N-succinyl-chitosan hydrogels, as injectable systems towards tissue engineering.
(2) In preparing functionalized oxide surfaces on a chip.
(3) As a starting material to synthesize polyesters in presence of a metal triflate as a catalyst.
(4) As a cross-linking agent to enhance the mechanicalproperties and antimicrobial activities of zein films. | | Safety Profile | Experimental teratogenic effects. Moderately toxic by ingestion. A severe eye irritant. Mutation data reported. Questionable carcinogen with experimental neoplastigenic data. When heated to decomposition it emits acrid smoke and irritating fumes. See also ANHYDRIDES. | | Purification Methods | Crystallise the anhydride from redistilled acetic anhydride or CHCl3, then filter, wash with diethyl ether and dry it in a vacuum.
