Dodecanedioic acid Usage And Synthesis
  • DescriptionThis acid is used in the production of nylon (nylon - 6,12), polyamides, coatings, adhesives, greases, polyesters, dyestuffs, detergents, flame retardants, and fragrances. It is now produced by fermentation of long-chain alkanes with a specific strain of Candida tropicalis. Its monounsaturated analogue (traumatic acid) is described below.
  • Chemical Propertieswhite crystalline powder
  • UsesInduced mutation of dodecanedioic acid producing Candida tropicalis.
  • DefinitionChEBI: An alpha,omega-dicarboxylic acid that is dodecane in which the methyl groups have been oxidised to the corresponding carboxylic acids.
  • Purification MethodsCrystallise the dioic acid from water, 75% or 95% EtOH (solubility is 10%), or glacial acetic acid. [Beilstein 2 IV 2126.]
