2-Chloro-6-(trifluoromethyl)pyridine can be used in the synthesis of medicine, pesticide or biocidal product.
| [Chemical Reactivity]
2-Chloro-6-(trifluoromethyl)pyridine is stable under recommended storage conditions, it reacts with strong oxidizing agents, strong acids, strong bases. | [Synthesis]
General procedure for the synthesis of 2-chloro-6-trichloromethylpyridine from 2-chloro-6-trichloromethylpyridine: 2-chloro-6-trichloromethylpyridine (700 g, 3.03 mol, feed rate 1.24 g/min) and anhydrous hydrogen fluoride (936 g, 46.8 mol, feed rate 1.66 g/min) were added successively to a tubular reactor fitted with a preactivated chromium oxide-alumina catalyst (210 g) in a tubular reactor at a reaction temperature of 330 °C. The reaction products were cooled with ice water and collected. The reaction products were collected after cooling with ice water and extracted with dichloromethane. The extract was washed with 10% potassium hydroxide solution, and the organic layer was separated and concentrated to give 490.0 g of crude 2-chloro-6-trifluoromethylpyridine, which was analyzed by GC for 95.03% purity and 89% reaction yield. The crude product was purified by fractionation to obtain 2-chloro-6-trifluoromethylpyridine with 98.0% purity and 80.0% yield. | [References]
