실험 절차

In a reinforced glass reactor with a capacity of 5 ml 2 ml of dimethyl carbonate and 150 mg of 1,6-dinitrohexane and 100 mg of Au/CeO2 (1 wt % gold relative to cerium) are introduced. The reactor is closed and purged with N2 to remove oxygen from the solution. Then the reactor is charged at 15 bars of hydrogen and immersed in a silicone bath preheated at 90° C. The suspension is magnetically stirred for 8 hrs. After this time, the reactor is discharged at atmospheric pressure, opened and the mixture is filtered. A gas chromatography analysis revealed the presence of 1,6-bis (methoxycarbonylamino) hexane in an 85% yield.
