adipic acid

Product name adipic acid
GOST 10558-80
CAS 124-04-9

Adipic Acid (also called 1,6-hexanedioic acid) is a white, crystalline compound, dicarboxylic acid; slightly soluble in water and soluble in alcohol and acetone; can be easily sublimed.

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, after rectification of this mixture to components, cyclohexanol is further reacted with nitric acid and air with a catalyst (copper or vanadium) or without nitric acid.

Uses.

  • Adipic acid consumption is linked almost 90% to nylon production by the polycondensation with hexamethylenediamine.
  • Adipic acid is used in manufacturing plasticizers and lubricants components.
  • Also it is used in making polyester polyols for polyurethane systems.
  • Food grade adipic acid is used as gelling aid, acidulant, leavening and buffering agent.
