Method for high-selectivity co-production of nitrocyclohexane and adipic acid

The invention relates to a method for the high-selectivity co-production of nitrocyclohexane and adipic acid, which adopts nitrogen oxide NOx as the nitrating and oxidizing agent, carrys out continuous gas-phase catalysis or non-catalytic nitration and oxidation reaction on cyclohexane. By effectively setting the conditions of the concentration ratio, the reaction temperature and the reaction time of the reactants and optimizing the reaction pressure as well as catalysts and assistants, the invention realizes the simultaneous high-selectivity co-production of the nitrocyclohexane and the adipic acid of different ratios, and the reduction product NO generated by the nitration and oxidation reaction can be recycled for cyclic utilization. The method of the invention has high resource efficiency, less waste generation, simple process flow and device and low production cost, and is an environment-friendly synthetic method.
