Abstract: Production of adiponitrile by introducing adipic acid in solid powder form or in liquid form and simultaneously introducing ammonia into a fluidized bed of a usual catalyst at a temperature of from 250* to 420*C and recovering the adiponitrile from the reaction gases by fractional distillation wherein there is added to the reaction gas before entry into the distillation column sufficient water to make the molar ratio of water vapor to ammonia 0.8 to 1.5 in the mixture entering the column. Adiponitrile is an intermediate in the manufacture of synthetic fibers of, for example, nylon 6.6.

Abstract translation: 通过以固体粉末形式或液体形式引入己二酸生产己二腈，同时在250-420℃的温度下将氨引入常规催化剂的流化床中，并通过分馏从反应气中回收己二腈，其中 在进入蒸馏塔之前，将反应气体加入到足够的水中以使进入塔的混合物中水蒸气与氨的摩尔比为0.8至1.5。 己二腈是制造例如尼龙6.6的合成纤维的中间体。

Abstract: PRODUCTION OF N-FORMYLMORPHOLINE OR N-ACETYLMORPHOLINE WHICH COMPRISES MIXING MORPHOLINE WITH FORMIC ACID OR ACETIC ACID AND DISTILLING OFF THE WATER FORMED FROM THE REACTION MIXTURE IN A COLUMN, A ZONE HAVING A TEMPERATURE OF FROM 130* TO 150*C. BEING MAINTAINED IN THE COLUMN ABOVE THE POINT OF SUPPLY AND A ZONE HAVING A TEMPERATURE OF FROM 210* TO 230*C. BEING MAINTAINED BELOW THE POINT OF SUPPLY. N-FORMYLMORPHOLINE AND NACETYLMORPHOLINE ARE SUITABLE AS EXTRACTANTS FOR AROMATIC HYDROCARBONS FROM HYDROCARBON MIXTURES.
