氯乙酰氯［ｍｏｎｃｈｌｏｒａｃｅｔｙｌｃｈｌｏｒｉｄｅ ,简称为ＣＡＣ］是强的酰化剂 ,氯乙酰化剂和环酰化剂 ,在有机合成中获得了广泛应用 ,已成为精细化工中重要的中间体。ＣＡＣ的分析通常采用测沸程或采用对氯乙酰氯的衍生物进行定量分析 。

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。

为此，滕州市浩瀚色谱仪器技术服务有限公司，，以科学发展为指导，，，色谱工程研究所，分析与测试中心，3个科研单位，研发出HHLYS3698-30氯乙酰氯直接进样测定专用毛细管柱通过直接进样对氯乙酰氯的含量进行分析。结果表明，此法分离效果好，准确度高，可用于氯乙酰氯工业生产的中间控制和产品质量分析。

Chloroacetyl chloride [monarchary type, referred to as CAC] is a strong acylating agent, chloroacetylating agent and cyclic acylating agent, has been widely used in organic synthesis, has become a very important intermediate in fine chemical industry. CAC analysis usually uses boiling range or quantitative analysis of chloroacetyl chloride derivatives.

Chloroacetyl chloride is widely used as an acylating agent in the synthesis of drugs and pesticides. One of the analysis methods for acid chloride is to react amide and acid with ammonia or amine and acid chloride to measure the content of acid chloride (Ind Eng Chem, Anal ed 1946, 18:444). In addition, the method of analyzing the reaction of alcohol with acid chloride to form ester and acid (Analyst 1953, 78:675) is superior to the previous method, but the author found that this method has a large error. The reason is that the esterification reaction of chloroacetyl chloride and alcohol is intense, and part of the hydrogen chloride and chloroacetyl chloride are easy to escape, resulting in low analysis results.

To this end, Tengzhou Haohan Chromatography Instrument Technology Service Co., Ltd. keeps pace with the times and is guided by scientific development. Under the leadership of Manager Wang Xiaoying, relying on Xiangying Analytical Technology Institute, Chromatography Engineering Institute, Analysis and Test Center, 3 A scientific research unit developed the HHLYS3698-30 Chloroacetyl Chloride Direct Injection Determination Capillary column to analyze the content of chloroacetyl chloride by direct injection. The results show that this method has good separation effect and high accuracy, and can be used for intermediate control and product quality analysis of chloroacetyl chloride industrial production.
