| titleOfInvention | A kind of catalyst for producing isophthalonitrile, preparation method and method for preparing isophthalonitrile with the same |
| abstract | The invention discloses a catalyst for producing isophthalonitrile, a preparation method and a method for preparing isophthalonitrile by using the catalyst. The catalyst adopts silica as a carrier, and the general formula of active components in terms of atomic ratio is: : Pb 1.0 Zr a As b Ag c X d Y e Z f O x , wherein X is selected from one or more of Ga, In, Tl and Nd, and Y is selected from one of Sr, Pd, Rb and Te one or more, Z is selected from one or more of Se and Ge. The activated catalyst is prepared by catalyst slurry preparation, drying and calcination, and the obtained catalyst has high conversion, selectivity, stability and no The characteristics of by-products of amides are beneficial to large-scale industrial clean production applications. |
