?氯乙酰氯是一種重要的農(nóng)藥中間體,可用于甲草胺、丁草胺、樂(lè)果、氧樂(lè)果等農(nóng)藥的合成。
采用正丁醇與氯乙酰氯和其他酰氯化合物進(jìn)行酯化,0.1％麝香草酚酞作指示劑,1摩/升的氫氧化鈉水溶液中和酯化反應(yīng)放出的氯化氫,中和到pH 6～8,再加內(nèi)標(biāo),取上層有機(jī)相進(jìn)行氣相色譜分析；此法操作復(fù)雜，費(fèi)時(shí)費(fèi)力，不環(huán)保，效率低下，無(wú)法滿足工業(yè)生產(chǎn)檢測(cè)的需要，使用受限。

Chloroacetyl chloride is an important pesticide intermediate that can be used for the synthesis of pesticides such as metoclopramide, butachlor, dimethoate, and oxytetracycline.
Esterification of n-butanol with chloroacetyl chloride and other acyl chloride compounds, using 0.1% thymolphthalein as an indicator, neutralizing the hydrogen chloride released from the esterification reaction with 1 mol/L sodium hydroxide aqueous solution to pH 6-8, adding an internal standard, and taking the upper organic phase for gas chromatography analysis; This method is complex, time-consuming, labor-intensive, environmentally unfriendly, inefficient, and cannot meet the needs of industrial production testing, limiting its use.
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has developed a specialized capillary chromatography column for the determination of industrial chloroacetyl chloride. The column is capable of directly injecting samples to determine the purity of industrial chloroacetyl chloride, with high efficiency, column efficiency, short analysis time, and satisfactory results.
Name: Capillary Column
Specification: 30m * 0.32mm
Model: HHLYS3698-30
Application: Determination of industrial chloroacetyl chloride/dichloroacetyl chloride/trichloroacetyl chloride
