    Abstract: PROBLEM TO BE SOLVED: To easily and safely produce adiponitrile useful as a production raw material for hexamethylenediamine useful as a raw material for nylon 66 (an industrial resin) and as a raw material and intermediate for various chemicals in high yield. SOLUTION: The objective adiponitrile is produced by reacting 1-formyloxy-2- nitrosocyclohexane or 1-hydroxy-2-nitrosocyclohexane with formic acid and hydroxylamine preferably at 60-130 deg.C in liquid phase under normal pressure or positive pressure. Preferably, the amounts of the reagents are 1-5 times mol for hydroxylamine, 10-300 times weight for formic acid and 1-300 times weight for the reaction solvent (e.g. acetonitrile or formic acid) based on the 1-formyloxy-2-nitrosocyclohexane or 1-hydroxy-2-nitrosocyclohexane (in terms of monomer), respectively. The hydroxylamine is preferably used usually in the form of sulfate, hydrochloride, etc. The compound is easily separable from the system by distillation.

    Abstract: PURPOSE: To highly easily obtain the subject compound useful as a raw material for producing hexamethylenediamine, etc., in a high yield and in a high selectivity by reacting 1-formyloxy or hydroxy-2-nitrosocyclohexane with an inorganic base and hydroxylamine. CONSTITUTION: This method for producing 1,6-dioxyiminohexane comprises reacting (A) 1-formyloxy-2-nitrosocyclohexane or 1-hydroxy-2-nitrosocyclohexane with (B) an inorganic base such as the hydroxide, (bi)carbonate, etc., of an alkali(ne earth) metal and (C) hydroxylamine e.g. in amounts of 1-10 equivalents and l-5 equivalents, respectively, based on the component in terms of the monomer. The reaction is preferably performed in a reaction solvent such as a 1-4C aliphatic alcohol or water at 70-100 deg.C under the atmospheric pressure or an elevated pressure.
