Abstract: A carbocyclic or heterocyclic compound, ammonia and an oxygen-containing gas are subjected to fluid catalytic reaction in vapor phase in the presence of a catalyst containing alkali metal to produce an aromatic or heterocyclic nitrile. The use of the catalyst containing a specific amount of alkali metal enables the stable production of the aromatic or heterocyclic nitrile in high yields with little change with time even when water is present in the reaction system. The use of the catalyst containing the alkali metal also enables the recycle and reuse of unreacted ammonia which is usually accompanied by water, thereby reducing production costs.

Abstract translation: 在含有碱金属的催化剂存在下，将碳环或杂环化合物，氨和含氧气体在气相中进行流化催化反应以产生芳族或杂环腈。 使用含有特定量的碱金属的催化剂能够以高产率稳定地生产芳族或杂环腈，即使在反应体系中存在水时也几乎不改变。 使用含有碱金属的催化剂也能够再循环和再利用通常伴有水的未反应的氨，从而降低生产成本。

Abstract: There is disclosed a process for producing a nitrile compounds by ammoxidation of a carbocyclic or heterocyclic compound having organic substituent(s) by reacting the compound with ammonia and an oxygen-containing gas, wherein unreacted ammonia is recovered from the reaction product gas and recycled to the reaction system.
