Caprolactam is an amide and, therefore, undergoes the reactions of this class of compounds. It can be hydrolyzed, Ai-alkylated, O-alkylated, nitrosated, halogenated, and subjected to many other reactions (3). Caprolactam is readily converted to high molecular weight, linear nylon-6 polymers. Through a complex series of reactions, caprolactam can be converted to the biologically and nutritionally essential amino acid L-lysine (10) (see Amino acids). 

Nylon, nitrosated with dinitrogen trioxide according to Belg. Pat. 606 944 and stored cold, exploded on being allowed to warm to ambient temperature. The N-nitroso nylon would be similar in structure to iV-nitroso-iV-alkylamides, some of which are thermally unstable. Nylon components should therefore be excluded from contact with nitrosating agents.

Linear polymer obtained by polymerization of e-caprolactam, q.v. Schlack, US. pat. 2,241,321 (1941 to I. G. Farbenind.). The importance of this fiber increased with the discovery that caprolactam can be produced by the nitrosation of cyclo-hexanecarboxylic acid Muench et al, U.S. pats. 3,022,291 and 3,108,896 (1962, 1963, both to Snia Viscosa).
