Synthetic method of 2-fluorine-6-tirfluoromethylpyridine

The invention belongs to the field of pesticide intermediate synthesis, and more specially relates to a synthetic method of 2-fluorine-6-tirfluoromethylpyridine. According to the synthetic method, 2-chloro-6-tirchloromethylpyridine and anhydrous hydrogen fluoride are taken as raw materials, under the effect of a catalyst, reaction is carried out at 70 to 150 DEG C 2 to 4.0MPa so as to obtain a 2-fluorine-6-tirfluoromethylpyridine crude product, and purifying is carried out so as to obtain 2-fluorine-6-tirfluoromethylpyridine; the catalyst is mixed antimony halide. The preparation method is simple; the raw materials are cheap and easily available; technology route is simple; no solid waste is generated; product yield is higher than 95%; product content is higher than 99%; waste gas hydrogenfluoride and hydrogen chloride are absorbed by an alkaline solution; and almost no environment pollution is caused.
