    • PURPOSE: An ammoxidation reactive catalyst, and a method of manufacturing dicyano benzene using the same are provided to secure the reaction safety as the reaction heat is able to be easily controlled even when the ammoxidation reaction of xylene is performed in a fixed-bed reactor, and to require no use of dilute gas contrary to the conventional ammoxidation reactive catalyst. CONSTITUTION: An ammoxidation reactive catalyst includes catalyst activation components, and a carrier component containing TiO2 and metal borate. The catalyst activation components include an oxide comprising: vanadium(V); chrome(Cr); molybdenum(Mo), tungsten(W) or both of them; at least one element selected from alkali metals or alkaline earth metals; and manganese(Mn), or another oxide comprising: vanadium(V); chrome(Cr); molybdenum(Mo), tungsten(W) or both of them; at least one element selected from alkali metals and alkaline earth metals; manganese(Mn); and at least one element selected from the group consisting of zinc(Zn), tin(Sn), bismuth(Bi), indium(In), lead(Pb) and antimony(Sb).
    • 目的:提供氨氧化反应催化剂和使用其制备二氰基苯的方法,以确保反应安全性,因为即使在固定床反应器中进行二甲苯的氨氧化反应,反应热也能够容易地控制, 并且不需要使用与常规氨氧化反应催化剂相反的稀释气体。 构成:氨氧化反应催化剂包括催化剂活化组分和含有TiO 2和金属硼酸盐的载体组分。 催化剂活化组分包括氧化物,其包含:钒(V); 铬(Cr); 钼(Mo),钨(W)或它们两者; 至少一种选自碱金属或碱土金属的元素; 和锰(Mn)或另一种氧化物,包括:钒(V); 铬(Cr); 钼(Mo),钨(W)或它们两者; 至少一种选自碱金属和碱土金属的元素; 锰(Mn); 以及选自锌(Zn),锡(Sn),铋(Bi),铟(In),铅(Pb)和锑(Sb)中的至少一种元素。
