Abstract:
Cyclohexanone (ONE) is first produced via oxidation of cyclohexane by air at
16S'C and 10.7 bar. Yield of ONE is 81 mole percent. A hydroxylamine
solution is then contacted with the ONE to produce the cyclohexanone oxime.
Caprolactam is produced by Beckmann rearrangement in the presence of oleum
and ammonia. Caprolactam is produced after purification in cation columns
by ion exchange by distillation, condensation and flaking.
