Succinic anhydride Usage And Synthesis
  • DescriptionSuccinic 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 Propertiesfine white crystalline solid
  • UsesIt 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.
  • UsesSuccinic 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.
  • ApplicationAlkyl succinic anhydride (ASA) is used as a sizing agent or wet strength additive in paper production.
  • General DescriptionColorless 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 ReactionsReacts slowly with water. Insoluble in water.
  • Reactivity ProfileSuccinic 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 HazardFlash point data for Succinic anhydride are not available, however, Succinic anhydride is probably combustible.
  • Safety ProfileExperimental 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 MethodsCrystallise the anhydride from redistilled acetic anhydride or CHCl3, then filter, wash with diethyl ether and dry it in a vacuum. [Beilstein 17 H 606, 17 V 6.]
