Definition of 2B4 Caprolactam, Glyoxal and Glyoxylic Acid Production Source Category
Most of the annual production of caprolactam (NH(CH2)5CO) is consumed as the monomer for nylon-6 fibres and plastics, with a substantial proportion of the fibre used in carpet manufacturing. All commercial processes for the manufacture of caprolactam are based on either toluene or benzene. This subcategory also covers production of glyoxal (ethanedial) and glyoxylic acid production. The main greenhouse gas emitted from this subcategory is nitrous oxide.
