Abstract
Procedure for the continuous preparation of cyclohexanone by reaction of cyclohexanone in an oxime synthesis zone, counter-flow with a buffered aqueous solution of hydroxylammonium dihydrogen-phosphate, starting from a solution of hydroxylammonium salt which, in addition to at least 0.7 moles/kg of nitrate, contains free phosphoric acid, alkaline or ammonium salts, phosphoric acid and, if desired, the corresponding sulfuric acid salts, and has a pH value of 1.3 - 2.0 measured with a pH meter, this procedure being characterized in that the starting solution containing hydroxylammonium salt has a content of hydroxylammonium salt equal to or greater than 0.5 mol/kg and a concentration of salts and dissolved acids -in addition to nitrate-greater 1 mol/kg, and because it discharges a solution virtually depleted of hydroxylammonium and that does not contain more than 0.9 kg of cyclohexanone per kg of oxime produced.
