Abstract
Process for obtaining caprolactam by nitrization of cycloexilic compounds having a tertiary carbon atom, in particular, exahydrobenzoic acid and its functional derivatives, characterized in that the initial cycloalkyl compound is continuously nitrized in the presence of cycloexan in an amount such that it is maintained by effect of its continuous evaporation the reaction temperature in a short interval in the vicinity of the boiling point of the cited cycloexan, under the reaction conditions.
