| Abstract: | The capillary column was used to analyze acrylonitrile,and the organic impurities in the product could be separated under optimal conditions.Methyl ethyl ketone was used as the internal standard.By means of experiments and calculations,the relative weight calibration factor was obtained.The impurities in acrylonitrile were determined by capillary gas chromatography.The method was estab1ished with better accuracy,precision and reproducibility. |
