浩瀚工业氯乙酰氯含量的纯度及杂质测定专用毛细管柱HHLYS3698-50

氯乙酰氯作为酰化剂广泛用于药物和农药的合成。酰氯的分析方法之一是以氨或胺与酰氯反应生成酰胺和酸,从而测得酰氯的含量(Ind Eng Chem,Anal ed 1946,18:444)。另有以醇与酰氯反应生成酯和酸的分析方法(Analyst 1953,78:675)较前法为优,但作者发现,该法有较大误差。原因是氯乙酰氯和醇酯化时反应激烈,部分氯化氢与氯乙酰氯易于逸出,致使分析结果偏低。

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. keeps pace with the times and has developed a special capillary column for direct sampling determination of industrial chloroacetyl chloride and impurities dichloroacetyl chloride, trichloroacetyl chloride and chloroacetic acid, chloroacetic anhydride and other impurities, The area normalization method is used for quantification, and the result is accurate and reliable.
