A process for the production of hydrogen cyanide in the presence of an improved catalyst is disclosed. This improved catalyst is represented by the following empirical formula:
FeaCubSbcModMeeTefQgOh(SiO2)i
wherein Me is at least one element selected from the group consisting of V and W; Q is at least one element selected from the group consisttng of Mg, Zn, La, Ce, A, Cr, Mn, Co, Ni, Bi, U and Sn; and a, b, c, d, e, f, g, h and i each represents the atomic ratio of the elements in the formula for which they are subscripts, wherein for a= 10, b=0.5 to 5, c= 12 to 30, d=0 to 15, e=0 to 3, f=0 to 5, g=0 to 6, h=number of oxygen atoms as determined corresponding to the oxide formed by combining the above-described elements, and i=25 to 200. The process involves the vapour phase ammoxidation of methanol in the presence of the above catalyst. |
