Abstract: A recycling system for hydroxylamine formation and oximation is proposed. The recycling system includes a hydroxylamine formation zone, an oximation zone, a purification zone, and an adjusting zone having a nitrate absorption tower. An inorganic process solution, used by the recycling system, partially enters the nitrate absorption tower supplementing nitrate, followed by mixing with the residual inorganic process solution, thereby reducing the loss rate of hydroxylamine in the inorganic process solution due to degradation. In addition, the organic impurities with high boiling point in the inorganic process solution can be effectively removed in the purification zone. As a result, the reduced activity or selectivity of the catalyst for hydroxylamine formation, caused by the toxic effects of these organic impurities on the catalyst, can be avoided, and hence, a high concentration of hydroxylamine can be obtained.

Abstract: Provided is a process of producing cyclohexanone oxime comprising the steps of: pre-mixing an inorganic process solution containing a high concentration of hydroxylamine phosphate with a first stream of cyclohexanone such that the concentration of hydroxylamine phosphate is reduced to 80% or less of its initial concentration; and subjecting hydroxylamine phosphate in the premixed inorganic process solution to an oximation reaction with a second stream of cyclohexanone. According to the process, oximation is performed after the inorganic process solution containing a high concentration of hydroxylamine phosphate has been pre-mixed with the first stream of cyclohexanone to reduce the concentration of hydroxylamine phosphate. As a result, not only that the efficiency of oximation and the yield of cyclohexanone oxime are increased, but also the organic content of the inorganic process solution discharged from the oximation tower is reduced.
