Abstract: A process is disclosed for producing organic nitriles such as Acetonitrile or Hydrogen Cyanide, in which yields may exceed 90%, undesirable by-products are not produced, and handling of ammonia gas is avoided. In one aspect, a process includes preparing a feed including ammonium salts and water; introducing the feed into a reactor containing a catalyst; and heating the feed in the presence of the catalyst. The catalyst may advantageously include molybdenum on a silica or silica alumina support. The feed may be ammonium acetate in water with about 50 wt % ammonium acetate and the balance water or ammonium formate in water. In another aspect, a process includes preparing a feed including ammonium hydroxide and acetic acid; introducing the feed into a reactor containing a catalyst; and heating the feed in the presence of the catalyst.
