IMPROVED CATALYST FOR PRODUCTION OF ACRYLONITRILE AND HYDROGEN CYANIDE

PROBLEM TO BE SOLVED: To additionally increase a generation of byproducts of hydrogen cyanide with no considerable reduction in yield of nitrile. SOLUTION: A catalyst composition comprising a complex of catalytic oxides of iron, bismuth, molybdenum and calcium and characterized by the following empirical formula: AaBbCcDdFeeBifMo12Ox, wherein A= one or more of Li, Na, K, Rb and Cs or their mixture; B= one or more of Mg, Mn, Ni, Co, Ag, Pb, Re, Cd and Zn or their mixture; C= one or more of Ce, Cr, Al, Sb, P, Ge, La, Sn, V and W or their mixture; D= one or more of Ca, Sr, Ba or their mixture; a=0.01-1.0; b and e=1.0-10; c, d, and f=0.1-5.0; and x is a number determined by the valence requirements of the other elements present.
