Abstract: A method for synthesizing a ketoxime is provided. In a system of an aqueous carbonate solution, a reaction is performed on a ketone, ammonia and hydrogen peroxide by using a titanium-silicon molecular sieve as a catalyst to obtain the ketoxime. Moreover, a reaction progress is judged and an optimal reaction ratio is determined by a real-time monitoring of a pH value in a reaction system during the reaction. In the present invention, by monitoring the pH value in the reaction system, the progress of the reaction is judged, thereby determining the optimal reaction ratio. The pH of the system is further adjusted by an aqueous carbonate solution to increase the reaction velocity and conversion rate of the ammonia.
