| Application | 2, 6-difluoropyridine is widely used in the production of pharmaceuticals, pesticides, rubber and dyes; is an important intermediate of pesticide chemicals, used in the preparation of herbicides and insecticides, has important medicinal value and development prospects. |
| preparation | into a 500L enamel kettle, 252.2kg of sulfolane (1g/4ml) and 2, 6-dichloropyridine 50kg(1.0eq), then 43.2g of potassium fluoride (2.2eq) and 1.5kg of 18-crown -6(3%) were added in one time, stirred for 20min, then the temperature of the system is heated to 180~188 ℃, and the reaction is carried out at 180~188 ℃ for 6H. The product is transferred out of the reaction system by distillation in the reaction process, which drives the reaction to complete, the fractions were washed with water, separated, dried in organic phase, filtered, and the filtrate was Distilled. The fractions at 122~124 ℃ were collected, and the product was 30.4, yield 78.2%, GC purity: 99.5%. |
