名称：毛细管柱

规格：30m*0.32mm*0.5um

型号：HHLYS3698-30

应用：工业氯乙酰氯纯度及杂质二氯乙酰氯，三氯乙酰氯，氯乙酸，氯乙酸酐的测定

氯乙酰氯是一种重要的有机合成中间体，性质活泼，具有刺激性气味，主要应用于医药、农药、染料的合成，尤其在丁草胺、甲草胺、氟噻草胺等除草剂的生产中应用广泛。国内氯乙酰氯的生产主要以氯乙酸为原料，产品中含有氯乙酸、二氯乙酰氯、三氯乙酰氯等杂质。

氯乙酰氯的测定方法有化学滴定法和气相色谱法。其中，气相色谱法基本采用醇酯化，有研究直接稀释进样进行分析，酯化生成的酸对进样针及仪器均有腐蚀；有研究用碱调pH处理酯化生成的酸，取上清液进行分析，步骤较多，易产生误差。

浩瀚色谱（山东）应用技术开发有限公司，采用毛细管色谱法直接进样测定氯乙酰氯及其多氯杂质（二氯乙酰氯、三氯乙酰氯），操作简便、分离效果好，能满足科研及生产定量分析的要求。

HHLYS3698-30 Capillary Column Direct Injection Determination of Purity and Impurities of Industrial Chloroacetyl Chloride
HHLYS3698-30 Capillary Column Direct Injection Determination of Industrial Chloroacetyl Chloride Purity and Impurities Details:


Name: capillary column

Specifications: 30m*0.32mm*0.5um

Model: HHLYS3698-30

Application: Determination of industrial chloroacetyl chloride purity and impurities dichloroacetyl chloride, trichloroacetyl chloride, chloroacetic acid, chloroacetic anhydride


Chloroacetyl chloride is an important organic synthesis intermediate with lively properties and a pungent odor. It is mainly used in the synthesis of medicines, pesticides and dyes, especially in the herbicides such as butachlor, alachlor and flufenox. widely used in production. The domestic production of chloroacetyl chloride mainly uses chloroacetic acid as the raw material, and the product contains impurities such as chloroacetic acid, dichloroacetyl chloride and trichloroacetyl chloride.

The determination methods of chloroacetyl chloride include chemical titration and gas chromatography. Among them, gas chromatography basically uses alcohol esterification, and some studies directly dilute the sample for analysis, and the acid generated by esterification is corrosive to the injection needle and the instrument; some studies use alkali to adjust pH to treat the acid generated by esterification, take the The analysis of the clear liquid requires many steps and is prone to errors.

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. uses capillary chromatography to directly determine chloroacetyl chloride and its polychlorinated impurities (dichloroacetyl chloride, trichloroacetyl chloride) with simple operation and good separation effect, which can meet the needs of scientific research and Production quantitative analysis requirements.
