Process for the preparation of cyclohexanone oxime |
| abstract |
This invention relates to a process for the production of cyclohexanone oxime by reacting cyclohexanone with excess aqueous hydroxylamine in the presence of excess ammonia. More specifically, the invention relates to improving yields of the oxime while reducing undesirable by-product formation by use of two or more stages of reaction with correlated adjustment of reaction conditions in each stage. The invention also involves improved recovery of the unreacted hydroxylamine reactant for recycle in the process. |
