| Abstract: | The capillary-column gas chromatography was introduced for the determination of the impurities in caprolactam. And the impurity sorts and distribution at different stages of HPO process were analyzed by gas chromatography-mass spectrography. The qualitative analysis of the intermediates and end products was conducted. Beckmann rearrangement was considered as the main reason of impurity generation. |
