    Abstract: PROBLEM TO BE SOLVED: To develop a continuous aftertreatment method for oximization of a ketone such as a cycloalkane containing advantageously 8-20 carbon atoms, with which a catalyst is separated after the reaction, an oxime is separated from a reaction mixture, reaction water is separated from a solvent, a remaining alcohol is returned and in the operation, a product does not precipitate as a solid during the aftertreatment process.
    SOLUTION: A three component solvent system which comprises firstly one or a plurality of organic liquids perfectly or excellently miscible with water, for example, particularly an alcohol or an organic solvent partially miscible with water and an alcohol and has a boiling point higher than those of water and the alcohol is used. The miscibility gap of the three component solvent system by fluctuation of water content is utilized for extraction.
