Is caprolactam harmful?
Acute (short-term) exposure to caprolactam may result in irritation and burning of the eyes, nose, throat, and skin in humans. Chronic (long-term) exposure of workers to caprolactam has been observed to cause peeling of the hands and some eye, nose, and throat irritation, but no other effects on general health.
What is caprolactam used for?
Caprolactam is an intermediate primarily used in the production of nylon 6 fibres and resins. Around 68% of caprolactam is consumed in the production of nylon fibres for textile, carpet and industrial yarns with the rest used in engineering resins and films.
What is the structure of caprolactam?
What does caprolactam look like?
Caprolactam is a clear to milky white-colored solution with a mild, disagreeable odor. Contact may cause slight irritation to skin, eyes, and mucous membranes. May be mildly toxic by ingestion.
How is caprolactam made?
Caprolactam can be produced from cyclohexane, phenol, or toluene by the following four routes: From oyclohexane via cyclohexanone by oxidation, oximation, and Beckmann rearrangement. From phenol via cyclohexanone by hydrogenation, oximation, and Beckmann rearrangement.

What is the difference between caprolactam and caprolactone?
Although no longer economical, caprolactone was once produced as a precursor to caprolactam. Caprolactone is treated with ammonia at elevated temperatures to give the lactam: Carbonylation of caprolactone gives, after hydrolysis, pimelic acid.
Is caprolactam a petrochemical?
Caprolactam is a petrochemical product that goes into nylon-6 production, which in turn is a raw material for filament yarn, fishing nets, tyre cords and other products. With limited production capacity in the country, demand for caprolactam is big in the domestic market.
What is the raw material of caprolactam?
Caprolactam – It is manufactured from raw materials such as Benzene, Sulphur (as Sulphur-di-oxide and Oleum), Ammonia, Carbon-di-oxide.
What is the functional group of caprolactam?
Because ε-caprolactam is the only common caprolactam isomer, the ε is usually dropped. It derives its name from ε-aminocaproic acid, or 6-aminohexanoic acid; in principle, the lactam is formed when the terminal carboxylic acid and amino groups react to form the amide.
Why it is called epsilon caprolactone?
ε-Caprolactone or simply caprolactone is a lactone (a cyclic ester) possessing a seven-membered ring. Its name is derived from caproic acid. This colorless liquid is miscible with most organic solvents and water. It was once produced on a large scale as a precursor to caprolactam.
