ハロゲン化芳香族ニトリルの調製に適した流動床触媒、その調製および用途
Document Type and Number:
Japanese Patent JP7113066
Kind Code:
B2
Abstract:
Disclosed is a fluidized-bed catalyst suitable for the production of halogenated aromatic nitriles, its preparation and application thereof. The catalyst comprises an active component and a support, wherein the active component is a complex having the following composition expressed in atomic ratio: VPaCrbAcMdOx,wherein A represents at least one metal selected from the group consisting of alkali metals and alkaline earth metals; M represents at least one element selected from the group consisting of Ti, Zr, Hf, La, Ce, Nb, Mo, W, Co, Zn, Fe, Ni, B, Sb, Bi, As, Ga, Ge, Sn, and In; in the XRD spectrum of the catalyst, diffraction peaks are present at 2θ = 27.8 ± 0.5° and 2θ = 13.8 ± 0.5°, and the ratio of the height (I1) of the diffraction peak at 2θ = 27.8 ± 0.5° to the height (I2) of the diffraction peak at 2θ = 13.8 ± 0.5° is 3.5-6, i.e. I1: I2= 3.5-6. The catalyst shows an excellent ammoxidation activity, and can provide a high reaction conversion and selectivity in the absence of the dangerous chemical of bromoethane, when used in the production of halogenated aromatic nitriles, and thus is particularly suitable for use in industrial applications.
