Synthesis method of high-content 2, 2-dichloro-1-(1-chlorocyclopropyl) ethanone for quantitative and qualitative analysis

The invention belongs to the technical field of pesticide synthesis, and particularly relates to a synthesis method of high-content 2, 2-dichloro-1-(1-chlorocyclopropyl) ethanone for quantitative and qualitative analysis. According to the method, cyclopropylethanone or chlorinated cyclopropylethanone used as a raw material is chlorinated to obtain the target compound, which can be used for analyzing the impurities of a prothioconazole bulk drug, tracking the sources of the impurities, researching the generation mechanism of the impurities, speculating the properties of the impurities according to the structures so as to control generation of the impurities or find a method for removing the impurities, and finally further improving the quality of the prothioconazole bulk drug and reducing the influence of potential impurities caused by the use of the pesticide prothioconazole on environmental pollution and human body health. 本发明属于农药合成技术领域，具体涉及一种用于定量定性分析的高含量2,2-二氯-1-(1-氯环丙基)乙酮的合成方法。该方法以环丙基乙酮或者氯代环丙基乙酮为原料经过氯代得到该目
