                                         Information @ a Glance
  • Adipic acid (IUPAC systematic name: hexanedioic acid) is a dicarboxylic acid. It is a white crystalline powder. Due to its long aliphatic chain, it is not very soluble in water.
  • Adipic Acid is a C6 straight-chain dicarboxylic acid; slightly soluble in water and soluble in alcohol and acetone. Almost all of the commercial adipic acid is produced from cyclohexane through two sequent oxidation processes.
  • Adipic acid is a chemical intermediate used in the production of nylon 66 resin and nylon 66 fibre or in polyol and polyurethane production.


  • Almost all of the commercial adipic acid is produced from cyclohexane through two sequent oxidation processes.
  • The first oxidation is the reacting of cyclohexane with oxygen in the presents of cobalt or manganese catalysts at a temperature of 150 - 160 C, which produce cyclohexanol and cyclohexanone. Then, the intermediates are further reacted with nitric acid and air with a catalyst (copper or vanadium) or without nitric acid.
  • Most adipic acids react with 1,6-hexane diamine to form polyamide, more known by its product name "Nylon 6,6". Nylon 6,6 is mainly used to produce fibre and resins.


  • Adipic acid is used in manufacturing plasticizers and lubricants components. It is used in making polyester polyols for polyurethane systems. Food grade adipic acid is used as gelling aid, acidulant, leavening and buffering agent.
  • Adipic acid derivatives , acyl halides, anhydrides, esters, amides and nitriles, are used in making target products such as flavoring agents, internal plasticizers, pesticides, dyes, textile treatment agents, fungicides, and pharmaceuticals.
  • Nylon 6,6 fiber is used in apparel, especially ladies' hosiery, sleepwear, and underwear, carpets, and home furnishings. Other nylon 6,6 fiber uses include tire cord, fishing line, brush bristles, and in tough fabrics for parachutes, backpacks, luggage, and business cases.


  • The hexanedioic acid (HC) consumption structure varies by regions. Thus, in the Asia-Pacific region 85% of HC is used for polyamide production, while its share in the production of polyurethanes is lower, since polyurethane production in this region more often involves simple polyesters which do not require adipic acid for their synthesis.
  • Nevertheless, demand for nylon applied in the manufacture of plastics is growing. The Asian region is a vivid manifestation of this tendency. That, in turn, leads to the increase in the demand for AC in the region.
  • Russia fails to have its own production of adipic acid, though the prerequisites for its origination are quite favourable, since the vital feedstock is available and major consumers of end-products are present.


  • Nitrous oxide (N2O) is generated as a by-product during the production of adipic acid and nitric acid. The main use for adipic acid is as a component of nylon-6/6; thus production trends are closely correlated with nylon consumption trends.
  • Worldwide, there are very few adipic acid plants. The U.S. is a major producer with three companies in four locations accounting for approximately forty percent of world production.
  • Other producing countries include Brazil, Canada, China, France, Germany, Italy, Japan, Korea, Singapore, Ukraine, and United Kingdom.
  • Most of these countries have only one adipic acid plant. Nitric acid is used primarily to make synthetic commercial fertiliser. Worldwide, the number of nitric acid plants is somewhat uncertain.
