Frequently Asked Questions | FAQs

What is caprolactum?

Caprolactam is a cyclic amide and a key raw material used in the production of nylon 6. It is a white crystalline solid with a slightly bitter odor, and it has the chemical formula (CH2)5C(O)NH.
Caprolactam is produced through a process called the “ammonium sulfate process.” In this process, cyclohexanone oxime is first produced by reacting cyclohexanone with hydroxylamine, which is then rearranged into caprolactam by heating it in the presence of sulfuric acid. The resulting caprolactam can then be further processed to produce nylon 6 fibers, which are used in a wide range of applications such as textiles, carpets, and industrial materials.
Caprolactam is also used as a chemical intermediate in the production of other chemicals, such as adipic acid and hexamethylenediamine, which are used in the production of nylon 6,6.
