摘　　要：介绍了羟胺-环己酮法中环己酮肟化反应的原理及工艺流程,讨论了反应温度、环己酮进料的分布、缓冲溶液的pH值、脉冲速度等因素对肟化反应效率的影响,针对各个影响因素提出了改进肟化反应条件的措施并应用于生产实践,提高了肟化反应效率。The principles and process of cyclohexanone oximation in hydroxylamine-cyclohexanone process were introduced. Influencing factors such as temperature, feed-in distribution of cyclohexanone, pH value of buffer solution and pulse speed were discussed in detail. After some improvement measures were put forward and applied according to these factors, the efficiency of oximation reaction was increased.
