- 2 3 5-Trichloropyridine Introduction: It is a light yellow solid and an important fine chemical intermediate. 2,3,5-Trichloropyridine reacts with alkali metal hydroxides to prepare 3,5-dichloro-2-pyridinol, which is an important raw material for the synthesis of pesticides such as the insecticide Chemicalbook and the herbicide oxafen. 2,3,5-Trichloropyridine can also be further fluorinated to synthesize 2,3-difluoro-5-chloropyridine, which is the basic material for the synthesis of the herbicide clodinafop-propargyl.
- 2 3 5-Trichloropyridine put 60g methanol into a 1000mL four-necked flask, put in 100g 2,3,5,6-tetrachloropyridine, 31.7g hydrazine hydrate, raise the temperature to 60～65℃, keep the temperature for about 2 hours, the reaction is over, cool down Stir at 0～5°C for 1 hour, filter, and the solid is 2,3,5-trichlorohydrazinopyridine 6-hydrate. After drying, 101.6g of white solid is obtained, the yield is 96%, and the content is 98.5%. Add 100g of 2,3,5-trichlorohydrazinopyridine, 50g of 5% sodium hydroxide aqueous solution to a 1000ml four-necked flask with Chemicalbook, add 387.6g of 10% sodium hypochlorite aqueous solution dropwise. , Keep at 70～75℃, react for 1 hour, the reaction is over, cool to 5～10℃, stir for 1 hour, filter to obtain crude 2,3,5-trichloropyridine, and distill under reduced pressure to obtain the product, which is a light yellow solid. Yield: 95%, content: 98%.
