N'-(6-aminohexyl)hexane-1,6-diamine

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 0.4 liter/hour of adipodinitrile, 1.2 liter/hour of ammonia and 2.4 liters/hour of hydrogenation mixture are fed, at 270° C. and under an H2 pressure of 260 bar, into the reactor described in Example 1, and over the catalyst described in that Example. Azacycloheptane is obtained in a yield of 70% together with 3% of bishexamethylenetriamine, 7% of hexylamine and 15% of hexamethylenediamine. are fed, at 270° C. and under an H2

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: Bis(hexamethylene)triamine (8.62 g, 40 mmol) was dissolved in acetonitrile (120 ml). Water (0.864 ml) was added to the mixture. Ethyl trifluoroacetate (16.7 ml, 140 mmol) was added to the mixture cooled in an ice bath. After addition, the mixture was refluxed for 16 hours. The solvents were removed by evaporation. The residue solidified upon storing at room temperature and was used for next step without purification. cooled in an ice bath After addition the mixture was refluxed for 16 hours The solvents were removed by evaporation upon storing at room temperature was used for next step without purification
