| titleOfInvention | Method for producing 3-cyanopyridine by using fluidized bed and catalyst used in method |
| abstract | The invention provides a method for producing 3-cyanopyridine by using a fluidized bed and a catalyst used in the method, wherein 3-methylpyridine, ammonia gas, air and water in a molar ratio of 1 (8-20): 50-75): 20-25 are used as raw materials, and the raw materials are subjected to ammoxidation reaction to produce the 3-cyanopyridine in the presence of the catalyst used in the fluidized bed; the catalyst for the fluidized bed comprises gamma-Al 2 O 3 A powder and an active ingredient; the active components comprise vanadium pentoxide, chromium trioxide and auxiliary active components, the catalyst can be used for fluidized bed production of 3-cyanopyridine, has high catalytic activity, good selectivity and high yield of the product 3-cyanopyridine, and can be used for industrial production. |
