A cyclohexylamine is produced from a cyclohexane by reacting the latter in liquid phase with O2 in presence of a dehydrated form of boric acid at 75-300 DEG C. and 100-1000 p.s.i.g. to give a crude cyclohexanol mixture containing up to 15% cyclohexanone, and catalytically reacting this mixture at 130-500 DEG C. and 5-250 atm. with 2-10 mols. NH3 and 2-10 mols H2, per mol. of crude cyclohexanol. The cyclohexylamine may be reacted with H2O2 and a tungstate catalyst to give a cyclohexanone-oxime, which may be rearranged with conc. H2SO4 to the epsilon-caprolactam |
