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.

Abstract: PROBLEM TO BE SOLVED: To provide a production process for cyclic alcohols and cyclic ketones of 7-16 carbon atoms. SOLUTION: A cycloalkane of 7-16 carbon atoms is oxidized with an oxygen- containing gas in the presence of a slightly soluble transition metal catalyst in the group of 6-12 of the periodic table (for example, a transition metal complex, a transition metal complex salt or transition metal salt, particularly a transition metal phthalocyanine of substituted transition metal phthalocyanine) in the presence of a boron compound, particularly an acid of boron.

Abstract: PROBLEM TO BE SOLVED: To provide a method for a post treatment of a reaction mixture formed by performing an ammoxime formation of a ketone with hydrogen peroxide and ammonia by using a catalyst containing titanium in a homogeneous solution, including the separation of the catalyst, selective separation of an oxime formed in the ammoxime formation, sending out of the reaction water and return of a solvent as partial processes. SOLUTION: This post treating process has at least one membrane separation process. It is possible to perform the reaction even if the reaction ratio of the ketone is insufficient or even in the presence of a dissolved salt. COPYRIGHT: (C)2003,JPO
