聚己内酰胺生产中被氧化原因及预防措施

Reasons and prevention of polycaprolactam oxidation during its production

影响聚己内酰胺氧化的因素主要是氧含量、反应温度、反应时间、重金属盐及端氨基含量等,防止聚己内酰胺在生产中被氧化的措施主要是优化生产工艺参数,优选设备材质及原料等。

The primary factors affecting polycaprolactam oxidation included oxygen content, reaction temperature and time, heavy-metal salt and ammo end group. The polycaprolactam oxidation can be avoided during its production by optimizing process parameters, equipment material and raw materials.
