應(yīng)用：工業(yè)氯乙酰氯測定

氯乙酰氯是一種有機(jī)化合物，分子式為C2H2Cl2O，無色透明液體，有刺激性氣味，溶于丙酮，可混溶于乙醚。主要用作醫(yī)藥及農(nóng)藥的原料，尤其用于丁草胺、甲草胺等除草劑的生產(chǎn)。

酰氯的分析方法之一是以氨或胺與酰氯反應(yīng)生成酰胺和酸,從而測得酰氯的含量(Ind Eng Chem,Anal ed 1946,18:444)。另有以醇與酰氯反應(yīng)生成酯和酸的分析方法(Analyst 1953,78:675)較前法為優(yōu),但發(fā)現(xiàn),該法有較大誤差。原因是氯乙酰氯和醇酯化時(shí)反應(yīng)激烈,部分氯hua氫與氯乙酰氯易于逸出,致使分析結(jié)果偏低。

Purity determination of industrial chloroacetyl chloride
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
