Abstract
Abstract There is disclosed a catalytic composition represented by the formula: (Mo)a(W)b(Bi)c(Pb)d(Sb)e(A)f(B)g(C)h(P)m(O)n in which A is iron and/or chromium, B is cerium and/or magnesium and C is potassium and/or lithium; and a, b, c, d, e, f, g, h, m and n stand for the numbers of atoms for molybdenum, tungsten, bismuth, lead, antimony, A, B, C, phosphorus and oxygen elements respectively, wherein, given that a+b=12, 0</=b</=7, 0.4</=c</=7, 2</=d</=12, 0.1/22</=e/a</=25/22, 0.05/22</=f/a</=3/22, 0</=g/a</=2/22, 0</=h/a</=3/22, 0</=m/a</=7/22, and n is the numbers of oxygen necessary to satisfy the valences of atoms for the individual constituent elements other than oxygen.
