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 caprolactam made of?
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 do you mean by caprolactam?
: a white crystalline cyclic amide C6H11NO used especially in making one type of nylon.
What is caprolactam in chemistry?
ε-Caprolactam is a crystalline cyclic amide with a melting point of 70 °C. 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.
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 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.
What is another name for caprolactam?
Caprolactam (CPL) is an organic compound with the formula (CH2)5C(O)NH….Caprolactam.

Where does caprolactam come from?
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.
Is caprolactam a VOC?
Caprolactam is the major VOC emitted in nylon 6 heatsetting.
Is caprolactam a polymer?
ROTATIONAL MOLDING POLYMERS A single monomer, caprolactam as ε-amino caproic acid, H2N−(CH2)5−COOH, polymerizes head-to-tail in the presence of heat and a catalyst, to produce H2N–[–(CH2)5–CO–NH–(CH2)5–]n–COOH, Nylon 6 also known as polycaprolactam.
Is caprolactam a monomer?
Caprolactum is the monomer used for synthesizing the polymer, Nylon-6.
