Latest Patents
1. **Recycling System for Hydroxylamine Formation and Oximation**
Hsiu-Li Cheng's first patent provides a comprehensive recycling system that enhances the formation of hydroxylamine and its subsequent oximation. This system comprises several zones, including a hydroxylamine formation zone, an oximation zone, a purification zone, and an adjusting zone featuring a nitrate absorption tower. By optimizing the use of an inorganic process solution, which partially enters the nitrate absorption tower, the system effectively reduces the loss of hydroxylamine due to degradation, thus enabling the production of high concentrations of hydroxylamine free from toxic organic impurities.
2. **Process for Production of Cyclohexanone Oxime**
Her second patent outlines a method for efficiently producing cyclohexanone oxime. This innovative process involves pre-mixing an inorganic process solution containing hydroxylamine phosphate with cyclohexanone, reducing the concentration of hydroxylamine phosphate to 80% or less. This strategic pre-mixing step increases the efficiency of the oximation process, enhances the yield of cyclohexanone oxime, and minimizes the organic content discharged from the oximation tower.
