haohan工业氯乙酰氯含量的测定专用毛细管柱HHLYS3698-30

 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 analytical methods for acyl chloride is to react ammonia or amine with acyl chloride to generate amide and acid, thereby measuring the content of acyl chloride (Ind Eng Chem, Anal ed 1946, 18:444). Another analytical method (Analyst 1953,78:675) that generates esters and acids through the reaction of alcohols and acyl chlorides is superior to the previous method, but it was found that this method has significant errors. The reason is that the reaction between chloroacetyl chloride and alcohol esterification is intense, and some hydrogen chloride and chloroacetyl chloride are prone to escape, resulting in lower analysis results.



The HHLYS3698-30 specialized capillary column for chloroacetyl chloride developed and produced by Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. can be directly injected for analysis and quantified by area normalization method,; Acetyl chloride, dichloroacetyl chloride, trichloroacetyl chloride, chloroacetic anhydride, etc. were separated with satisfactory results.
