名称：毛细管柱

规格：30m*0.32mm*0.5um

型号：HHLYS3698-30

应用：工业氯乙酰氯测定

氯乙酰氯是一种有机化合物，分子式为C2H2Cl2O，无色透明液体，有刺激性气味，溶于丙酮，可混溶于乙醚。主要用作医药及农药的原料，尤其用于丁草胺、甲草胺等除草剂的生产。

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hua氢与氯乙酰氯易于逸出,致使分析结果偏低。


滕州市浩瀚色谱仪器技术服务有限公司，，研发出工业氯乙酰氯分析专用毛细管柱，直接进样测定，氯乙酰氯，二氯乙酰氯，三氯乙酰氯，氯乙酸，氯乙酸酐得到有效分离，柱效高，分离好。

此柱可扩展为：二氯乙酰氯，三氯乙酰氯的纯度分析

Industrial chloroacetyl chloride purity determination Details:

Name: Capillary Column

Specification: 30m*0.32mm*0.5um

Model: HHLYS3698-30

Application: Determination of industrial chloroacetyl chloride


Chloroacetyl chloride is an organic compound with the molecular formula C2H2Cl2O. It is a colorless transparent liquid with a pungent odor. It is soluble in acetone and miscible in ether. Mainly used as raw materials for medicine and pesticides, especially for the production of herbicides such as butachlor and alachlor.

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). Another analytical 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 it is found that this method has larger errors. The reason is that chloroacetyl chloride and alcohol react fiercely during esterification, and part of the chlorine hua hydrogen and chloroacetyl chloride are easy to escape, resulting in low analysis results.


Tengzhou Haohan Chromatography Instrument Technology Service Co., Ltd. keeps pace with the times and has developed a special capillary column for the analysis of industrial chloroacetyl chloride, direct injection determination, chloroacetyl chloride, dichloroacetyl chloride, trichloroacetyl chloride, chloroacetic acid, ethyl chloride The acid anhydride is effectively separated, the column efficiency is high, and the separation is good.

This column can be extended to: purity analysis of dichloroacetyl chloride and trichloroacetyl chloride
