2-氯-5-三氯甲基吡啶是重要的农药中间体。以3-甲基吡啶为原料通过光氯化反应合成2-氯-5-三氯甲基吡啶,经分离后得到纯度为99.5%的产品。利用红外(IR)、紫外(UV)、质谱(MS)、核磁共振(NMR)等实验技术研究了其波谱学特征,详细讨论了该化合物的1HNMR1、3CNMR谱,并对所有1HNMR、13CNMR谱的信号进行了归属。讨论了红外吸收特征峰对应官能团的振动形式,样品的官能团与目标化合物一致。该方法为此类化合物的结构解析提供了有益的分析依据。
2-Chloro-5-trichloromethyl pyridine is an important pesticide intermediates. 2-Chloro-5-trichloromethyl pyridine was synthesized by photochlorination using 3-methylpyridine as raw material, and the product was obtained after the separation to obtain a purity of 99.5%. Their spectroscopic properties were studied by means of IR, UV, MS and NMR techniques. The 1HNMR1,3CNMR spectra of the compounds were also discussed in detail. All 1HNMR and 13CNMR spectra The signal is attributed. The vibrational forms of the functional groups corresponding to the infrared absorption peaks are discussed. The functional groups of the samples are consistent with the target compounds. This method provides a useful analytical basis for the structural analysis of these compounds.
