2-氯-5-三氟甲基吡啶和2,3-二氯-5-三氟甲基吡啶是当今新型农药的重要中间体,其纯度对产物的制备和收率都有重要的影响。从红外光谱、核磁共振、高效液相色谱等谱学方法比较系统地分析了其谱学性质。
2-Chloro-5-trifluoromethylpyridine and 2,3-dichloro-5-trifluoromethylpyridine are important intermediates of today’s novel pesticides. The purity of 2-chloro-5-trifluoromethylpyridine has an important influence on the preparation and yield of the product. The spectroscopic properties were systematically analyzed by the methods of infrared spectroscopy, nuclear magnetic resonance and high performance liquid chromatography.
