Caprolactam Usage And Synthesis
Production of polyamide fibers and resins Caprolactam is the main raw material for the production of polyamide fiber and resin. Polyamide fiber, in the United States, is called nylon; in China, is called Chinlon because it was first commercialized in Jinzhou Petrochemical. Chinlon 66 is a polycondensation product of adipic acid and hexamethylene diamine. Polyamide 6 obtained from the ring-opening polymerization of caprolactam.
At present, the master of caprolactam production technology is mainly Sinopec Baling Petrochemical Design Institute and Yueyang Petrochemical Design Institute.
