| titleOfInvention | Ammoxidation catalyst, process for producing the same and process for producing isophthalonitrile |
| abstract | The invention discloses an ammoxidation catalyst, a preparation method thereof and a method for preparing m-phthalonitrile, wherein the active components of the catalyst satisfy the following general formula: v 1.0 Pb a Pd b A c B d C e O x (ii) a Wherein A is one or more of Fe, Co, Ni, K, Rb and Cs, B is one or more of Ir, Pt, Rh and Ru, and C is one or more of Nd, Pr, Ce and La; a is 0.05 to 2, b is 0.01 to 2, c is 0.01 to 5, d is 0.001 to 2, e is 0.001 to 0.9, and x is a value determined by the degree of oxidation of each element. The catalyst is used for preparing m-phthalonitrile from m-xylene through ammoxidation, reaction activation energy can be effectively reduced in the ammoxidation by accurately controlling the proportion of Pb and Pd, the conversion rate of m-xylene is high at a lower reaction temperature, and the m-phthalonitrile has high selectivity and yield, so that the catalyst is suitable for industrialization. |
