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.
