摘要
简述了精己二酸生产工艺 ,论证了精己二酸色度、硝酸盐含量超内控指标原因 ,对两大主要影响因素———活性炭。
The manufacture techniques of the refined hexandioic acid was related,the reasons that the refined hexandioic acid-chroma and the content of nitrate exceeded the inner target was demonstrated. Measures to improve activated carbon and solve centrifugal machine problem of the system were suggested.
