Abstract: Forming caprolactam from a nitrosating agent and at least 1 cyclohexanoyl cpd., selected from hexahydrobenzoic acid, derivs. which hydrolyse to the acid or ketones in which a cyclohexane ring is attached to the ketone carbonyl group, in the presence of SO3 or H2SO4, consists of feeding the cyclohexanoyl cpd. into the first of many reaction zones into which is also fed the nitrosating agent in an amt. not exceeding 65% by wt. of the overall wt. fed into all the reaction zonex, allowing reaction to proceed and then passing the mixture of reacted cyclohexanoyl cpd. and unreacted cyclohexanoyl cpd. into at least 1 other reaction zone into which is passed nitrosating agent in an amount not exceeding 65% by wt. of the overall amt. fed into all the reaction zones and here allowing the reaction to proceed.
