Latest Patents

One of Hongnian Shang's notable patents is the "Solvent-free green ammoximation process based on film distribution." This invention relates to a solvent-free process that utilizes membrane distribution. The procedure involves adding TS-1 catalyst and ketone into a reactor, setting the stirring speed and reaction temperature, and then introducing ammonia and hydrogen peroxide into the reaction solution. The hydrogen peroxide is distributed using a membrane, while ammonia is fed continuously or semi-continuously. This process results in the production of oxime. The advantages of this invention include mild reaction conditions, high efficiency, simple operation, and an environmentally-friendly approach. Notably, there is no need for any solvent during the reaction process, and both the conversion rate of the ketone and the selectivity of the oxime can exceed 98.0%.
