Caprolactam is e-caprolactam or lactam of epsilon-aminocaproic acid.
Molecular weight: 113.6.
White crystals or flakes.
Melting point: 70°C
Boiling point: 267°C
Density: 1.02 g/cm3.
Caprolactam is well soluble in water and in such organic solvents as alcohols, ethers, benzene. Caprolactam hydrolyzes in aqueous solutions of acids and alkalis and forms aminocaproic acid (H2N(CH2)5COOH).
JSC "Shchrkinoazot" produces caprolactam in the form of crystals or liquid by multi-stage synthesis from benzene via cyclohexanoxime rearrangement.
Two major raw materials for caprolactam manufacturing are benzene and phenol.
Caprolactam is mainly used as raw material for the production of nylon 6.
Specification - Caprolactam [-NH(CH2)5CO-]
