| Abstract: | A method of separation and preparation of 3-Br-2-methylpyridine and 5-Br-2-methylpyridine was studied by means of liquid chromatography using a sil-column and a mobile phase of a mixture of ether petroleum, ether and ammonia liquor in volume ratio 95:5:0.04. The purity of 3-Br-2-methylpyridine and 5-Br-2-methylpyridine was identified by HPLC. With the UV spectra of them, the UV coefficients of both were obtained. |
