摘  要:
2-氯-5-三氯甲基吡啶是重要的医药和农药中间体。研究用萃取、蒸馏以及柱色谱方法对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99%以上。

摘  要:
2-Chloro-5-trichloromethylpyridine is an important intermediate of many medicines and pesticides. The study used extraction, distillation and column chromatography to separate and purify those photochlorinated products of 3-methylpyridine. We examined the purity through capillary column GC, the result indicated that purity of the product surpassed 99%.
