Abstract

A mixture of monochloro-e -caprolactams, mainly b - and g -chloro, is obtained by irradiating with light a mixture of monochlorocyclohexane and a nitrosation agent at -20 DEG to 50 DEG C., and subjecting the resulting monochlorocyclohexanone oxime hydrochloride to a Beckmann rearrangement at 90-150 DEG C., directly or after neutralization to free oxime. Specified nitrosation agents are NOCl, NO + Cl2, NO + NO2 + HCl, NOCl + HCl, and NO + Cl2 + HCl. Some caprolactam is also obtained in the examples, and one example also prepares cyclohexanone oxime hydrochloride from cyclohexane.
