The synthetic method of sodium caprolactam is presented.

Effect of ultraviolet on Phanerochaete chrysosporium for decomposing caprolactam and degrading polyamide 6;

The research to the properties of soybean degradable material that modified by caprolactam;

Research on the Kinetics of Anionic Polymerization of Caprolactam to Nylon Using Adiabatic Method;

By means of anionic ring-opening copolymerization, a series of copolymers of ε-Capro-lactone with ε-caprolactam were synthesized at different lactam/lactone ratio, with the sodium hydroxide as catalyst, the aromatic diisocyanate as initiator, respectively.

Recent development of vapor - phase Beckmann rearrangement of cyclohexanone oxime to ε-caprolactam catalyzed by molecular sieves was reviewed.

The effects of preparation methods of TiO 2-ZrO 2 on catalytic performance of B 2O 3/TiO 2-ZrO 2 for vapor-phase Beckmann rearrangement of cyclohexanone oxime to ε-caprolactam were investigated.

The trends of direct oxidation of cyclohexanone to hexanolactam and developments of different routes in preparation of feed stocks of nylon-66 are also described.

Hydrofining is used to obtain high-quality hexanolactam with Raney-Ni as the preferred catalyst.

The corrosion behavior and protective methods of three typical stainless steel heat exchangers in hexanolactam apparatus were studied in this paper.

Reasons and prevention of polycaprolactam oxidation during its production;

Silver sol was prepared from silver nitrate by chemical reduction with sodium hypophosphite as a reducer and was added into polycaprolactam 6 (PA 6)/formic acid spinning solution with 12% PA 6 by mass fraction under different proportions to produce silver-containing PA 6 nanofiber by electrospinning process.

The production process of polycaprolactam is complicated and there are many factors affecting it.
