| 摘要 |
Acrylonitrile is prepared by reacting in the vapor phase at an elevated temperature propylene, molecular oxygen, and ammonia in the presence of a catalyst which comprises a multi-metal oxide composition comprising the metal elements antimony, tin, titanium, copper and/or iron. The catalyst may also contain an additional metal such as magnesium, zinc, vanadium, uranium, chromium, manganese, molybdenum, tungsten, cobalt, nickel, indium, arsenic, bismuth or tellurium. Use of such a catalyst improves the yields of acrylonitrile. |
