OXAMIDINATION PROCESS OF CARBONYL COMPOUNDS

摘要

This invention relates to a oxamidination method of carbonyl compounds comprising reacting a liquid-phase reaction system containing carbonyl compounds, ammonia and hydrogen peroxide in the presence of silicon containing catalyst, which characterized in that a liquid silicon-containing assistant is added to the reaction system, thereby the silicon concentration of the system arrived at 0.1-10000ppm. The method allows to reduce inactivation of catalyst caused by dissolution of silicon contained in the catalyst, extend catalyst life and improve stable operating time.
