Embodiment 1
[0030] In the hydroxylamine-oximation circulation system, the oximation reaction is carried out to form cyclohexanone oxime, and the phosphate inorganic treatment solution after extraction and separation is carried out. The total carbon content, the total content of cyclohexanone and cyclohexanone oxime, and the content of toluene in the inorganic treatment liquid were measured, and the results are recorded in Table 1.
[0031] Utilize stripping device of the present invention, under the pressure of 1atm and the temperature condition of 110 ℃, use low-pressure steam (5kg / cm 2 , 161°C) for stripping. The total carbon content, the total content of cyclohexanone and cyclohexanone oxime, and the content of toluene of the inorganic treatment liquid after stripping were measured, and the results are recorded in Table 1.
[0032] Total carbon content (ppm)
