Working up the ammoximation per products of ketones by liquid - liquid - extraction in a ternary solvent system

摘要

The invention relates to a method for working up of a reaction mixture which, by the ammoximation of a ketone with hydrogen peroxide and ammonia to a titanium-containing catalyst in a homogeneous solution is formed, comprising the steps of removal of the catalyst from the reaction mixture, separation of the product, the solution abschleu of the water of reaction and return of the solvent, wherein the separation of the resulting ketone in the liquid phase with the use of at least one liquid - liquid - extraction takes place in a ternary solvent system.
