Method of producing cyclohexanone oxime, characterized by mixing 6 to 60 parts of an aqueous solution of hydrogen sulphide with 1 part of an aqueous solution of sodium nitrocyclohexane from 10 to 20% calculated as nitrocyclohexane to effect a reaction to produce cyclohexanone oxime, simultaneously add dilute sulfuric acid to the reaction mixture to maintain the ph of the mixture from 2 to 4 throughout the reaction, add immediately after such mixing, to the reaction mixture, an organic solvent immiscible with water to dissolve and separating the cyclohexanone oxime from the aqueous reaction medium, and separating the cyclohexanone oxime from the organic solvent.
