PURPOSE:To obtain a catalyst with a high yield and selectivity which is made of a metal oxide essentially composed of metal such as tin, antimony, lead, copper and chromium to produce unsaturated nitrile from olefine. CONSTITUTION:When producing an unsaturated nitrile such as acrylonitrile by reacting olefine such as propylene with ammonia and oxygen in gaseous phase under a high temperature, a composition of a catalyst shall be a metal oxide essentially composed of one or more kinds of metal such as tin, antimony, lead, copper and chromium. The catalyst thus formed enables the production of acrylonitrile or the like with a high selectivity despite a higher reaction rate of material gas. |
