  • Caprolactam is an organic compound which is a lactam of 6-aminohexanoic acid (e-aminohexanoic acid, aminocaproic acid).
  • Caprolactam is produced as clear liquid form and as a crystalline form.
  • Caprolactam occurs as white, hygroscopic flakes or crystals with a distinctive odour.
  • Caprolactam is soluble in water, cyclohexane, chlorinated hydrocarbons.
  • Caprolactam will be synthesised from cyclohexanol in three steps. First, cyclohexanol is oxidized to cyclohexanone using chromium (VI). cyclohexanone is converted into an oxime via reaction with hydroxylamine. The oxime is then rearranged into caprolactam through a Beckman rearrangement.
  • There are several different processes for producing caprolactam[1, 2], such as the DSM/HPO method, BASF-NO reduction method, and the SNIA toluene method.
  • Caprolactam is mostly produced from benzene through three intermediates; cyclohexane, cyclohexanone and cyclohexanone oxime.
  • Most of the caprolactam is synthesised from cyclohexanone via an oximation process using hydroxylammonium sulfate followed by catalytic rearrangement using the Beckmann rearrangement process step.
  • The recovery process of caprolactam from the reaction mixture starts with neutralization, which results in the formation of a crude caprolactam top phase and an aqueous ammonium sulfate layer.
  • The crude caprolactam layer is extracted with an organic solvent in the so-called forward extraction, which is followed by back-extraction with water.
  • The primary industrial use of caprolactam is as a monomer in the production of nylon-6.
  • Caprolactam is a raw material (monomer) for the polyamide-6 production with a wide application in the artificial fibre industry as well as a structural material in the motorization and electrotechnics industry.
  • Small amounts of caprolactam are also used in cross-linking for polyurethanes and in the synthesis of lysine.
  • The Polymerisation of Caprolactam together with tha catalyst and stabilizer was preferably carried out in a one stage technology using VK tube reactor.
  • Conventional caprolactam technology is based on the key intermediate cyclohexanone, which is usually produced by the oxidation of cyclohexane, but can also be made from phenol or toluene.
  • The nylon fibres market is mature at around 1%/year growth while demand for engineering resins is much more robust at 4-5%/year.
  • Overall long-term global growth for caprolactam is estimated in the range of 2-2.5%/year.
  • The long-term average caprolactam market price is used as the yardstick for evaluating and comparing the economic feasibility of building a new production plant.
  • The outlook for the caprolactam industry is about average for a mature commodity chemical in the recovering economy.
  • China is expected to continue to be an importer of caprolactam. China is expected to be able to produce 660,000 tonnes/year but with demand estimated at 1.0-1.1m tonnes, imports of 400,000-500,000 tonnes will still be needed.
  • The caprolactam and ammonium sulphate production at Fertilizers and Chemicals Travancore (FACT) is expected to resume soon after a gap of about four months with the company management placing orders for a consignment of 15,000 tonnes of sulphur costing $389.1 a tonne in the international market.
