The present invention provides a method for producing an oxime, comprising the step of an ammoximation reaction of a ketone with an organic peroxide and ammonia in the presence of a catalyst containing titanium and silicon oxide, wherein the catalyst containing titanium and a silicon oxide is a mesoporous silicate, and is subjected to a contact treatment with a silicon compound.
The present invention provides a method for producing an oxime by carrying out an ammoximation reaction of a ketone with an organic peroxide and ammonia in a solvent in the presence of a titanosilicate, characterized in that the reaction is carried out by feeding the ketone and ammonia to a reactor in which the solvent, the titanosilicate and the organic peroxide are charged.
An object of the present invention is to produce an oxime with a satisfactory yield by an ammoximation reaction of a ketone with a peroxide and ammonia.
Disclosed is a process for producing oxime, which comprises conducting an ammoximation reaction of a ketone with a peroxide and ammonia in the presence of a mesoporous titanosilicate. The peroxide is preferably an organic peroxide. The mesoporous titanosilicate is preferably a HMS type or MCM-41 type mesoporous titanosilicate. The ketone is preferably cycloalkanone.
