Treatment products ammoximation of ketones by liquid-liquid EXTRACTION in a ternary solvent system.

摘要

Process for the treatment of a reaction mixture formed by ammoximation of a ketone with hydrogen peroxide and ammonia over a catalyst containing titanium in homogeneous solution, characterized in that it comprises substeps - separating the catalyst from the mixture reaction - separation of the product, - removal of reaction water, and - recycling the solvent, and that the separation of the ketone oxime formed is performed using at least one liquid-liquid extraction in a ternary solvent system being constituted the solvent system ternary first by one or more fully or satisfactorily miscible organic liquids with water, secondly water and thirdly by an organic solvent miscible only partially with water and alcohol, whose boiling point is higher than boiling point of the alcohol and water.
