<P>PROBLEM TO BE SOLVED: To provide a catalyst for acrylonitrile synthesis which can synthesize acrylonitrile at a high yield, and a method of manufacturing acrylonitrile using the catalyst. <P>SOLUTION: A catalyst for acrylonitrile synthesis having a composition represented by Fe<SB>a</SB>Sb<SB>b</SB>C<SB>c</SB>D<SB>d</SB>Te<SB>e</SB>F<SB>f</SB>X<SB>x</SB>Y<SB>y</SB>Z<SB>z</SB>O<SB>g</SB>(SiO<SB>2</SB>)<SB>h</SB>is used. In the formula, component C is at least one element selected from the group consisting of Cu, Ni, and Co; component D is at least one element selected from the group consisting of Mo, W, and V; component F is at least one element selected from the group consisting of P an B; component X is at least one element selected from the group consisting of Sn, Ti, Zr, Nb, Ta, Cr, Ru, Pd, Ag, Al, Ga, In, Tl, Ge, As, Bi, La, Ce, Pr, Nd, and Sm; component Y is at least one element selected from the group consisting of Mg, Ca, Sr, Ba, Mn, Zn, and Pb; component Z is at least one element selected from the group consisting of Li, Na, K, Rb, and Cs; SiO<SB>2</SB>represents silica; when a=10, b=5 to 60, c=0.1 to 8.0, d=0.1 to 4.0, e=0.1 to 5.0, f=1.3 to 5.0, x=0 to 5, y=0 to 5, z=0 to 2, and h=10 to 200; g is an atom ratio of oxygen required to satisfy the valence of each of the above elements other than Si; and f/d=1 to 5. <P>COPYRIGHT: (C)2010,JPO&INPIT |
