摘要: A process for conducting long-term ammoxidation of propylene in the presence a metal oxide catalyst at temperature from 300° C. to 500° produce acrylonitrile and hydrogen cyanide, wherein each (A) elemental phosphorus or compound (B) tellurium is added as regenerating agent least once reaction system accordance with progress reaction, being when yields both cyanide are reduced, chosen yield reduced unchanged increased, thereby maintain high levels cyanide.
