- 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.
