Preparation method of heterogeneous cyclohexanone oxime
The invention discloses a preparation method of heterogeneous cyclohexanone oxime. The method includes the following steps that ammonia and hydrogen peroxide react to generate hydroxylamine under theeffect of a catalyst, then the hydroxylamine reacts with cyclohexanone to generate cyclohexanone oxime, cyclohexanone oxime is extracted in an extraction phase to complete the separation of an organicphase and an inorganic phase, the extraction phase enters subsequent processes after filtering, and after being subjected to membrane separation, and extraction-phase catalyst slurry is returned to an ammoximation reaction kettle to participate in a catalytic reaction again. The ammoximation reaction is performed in a solvent-free state, the use of organic solvents is avoided, the energy consumption is low, there are fewer side reactions and fewer by products, and the subsequent refining process has small pressure. As there is no solvent, the reaction space is saved, and compared with the solvent-containing ammoximation reaction using the same device for production, the yield is improved. A hydroxylamine mechanism serves as a reaction mechanism, the conversion frequency of the hydroxylamine mechanism is about 2.5 times of that of an imine mechanism at 80 DEG C, and the conversion rate of cyclohexanone is high.
