| titleOfInvention | A kind of high-purity dichloro acetonitrile reaction terminal determines method |
| abstract | The invention discloses a kind of high-purity dichloro acetonitrile reaction terminals to determine method, include the following steps: that the two chloroacetonitrile standard samples and acetamide chlcride of known purity are measured relevant chromatogram spectrogram and peak area with high resolution gas chromatography method by (1), the average value repeatedly measured is saved as peak area in such a way that multiple measurement is averaged, and the peak area of manually recorded pure water；(2) sample of purity to be measured is measured into relevant chromatogram spectrogram and peak area with high resolution gas chromatography method, peak area of normal concentration and step (1) middle formation in target substance peak area, impurity peak area, step (1) is updated to the content being calculated in working hour to two chloroacetonitriles, dichloro acetamide and water in test sample；Reach reaction end when two chloroacetonitrile purity are more than or equal to 99.5% and dichloroacetyl ammonia content is less than or equal to 0.2%, moisture content less than or equal to 0.1%.Advantages of the present invention: Concentration Testing had not only been ensured accurately but also can ensure that and reach reaction end. |
