Abstract: A process for the continuous separation of nitrocyclohexane from the gaseous products of cyclohexane vapour-phase nitration comprises partial condensation of said products, removal of fatty acids from the condensate by alkali washing, distillation to remove cyclohexane and water and further distillation-at sub-atmospheric pressure-of the nitrocyclohexane. The latter may be further purified by steam distillation, preferably in presence of a surface-active agent.
