Chloroacetyl chloride is widely used as an acylating agent in the synthesis of drugs and pesticides. One of the analysis methods of acid chloride is to react ammonia or amine with acid chloride to generate amide and acid, thereby measuring the content of acid chloride (Ind Eng Chem, Anal ed 1946, 18:444). In addition, the analysis method (Analyst 1953, 78: 675) that uses alcohol and acid chloride to react to produce esters and acids is better than the previous method, but the author found that this method has larger errors. The reason is that the reaction of chloroacetyl chloride and alcohol is fierce during esterification, and part of hydrogen chloride and chloroacetyl chloride are easy to escape, resulting in low analysis results.

Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. has developed a special capillary column to analyze chloroacetyl chloride by gas chromatography. The results show that this method has good separation effect and high accuracy, and can be used for intermediate control of chloroacetyl chloride industrial production and product quality analysis. .

The column is directly injected to determine impurities such as chloroacetyl chloride, dichloroacetyl chloride, trichloroacetyl chloride, chloroacetic acid and chloroacetic anhydride, with good results.
