Process for producing unsaturated acrylonitrile |
摘要 |
A process for producing acrylonitrile or methacrylonitrile, wherein a molybdenum compound, which is convertible to molybdenum oxide and not supported on a carrier is added to a fluidized bed reactor as an activator, in such a way that the ratio y of molybdenum atoms in the oxide catalyst represented by the formula: MoyBipFeqAaBbCcDdEeOf will be maintained in the range of 1.02x to 1.12x (x = 1.5p + q + a + c + 1.5d + 1.5e) during an ammoxydation reaction. |
