摘要
2-氯-5-三氯甲基吡啶是重要的医药和农药中间体.研究用柱色谱方法对3-甲基吡啶光氯化产物进行分离和提纯,制备高纯度的2-氯-5-三氯甲基吡啶.通过毛细管气相色谱检测纯度,结果表明产物纯度为90%以上.
chloro-5-trichloromethylpyridine is an important middle product of medicine and agricultural chemical. This article studies using pillar chromatography to separate and purify those products about lighting and chlorining 3-methylpyridine. We examine purity through capillary column gas chromatography.The result indicats that purity of the product is over 90%.
