Carbon Dioxide → 3-Aminobenzylamine

Participants

Reaction Steps

16.6 g (0.1 mol) of this m-nitrobenzaldoxime, 22 g (0.5 mol) of a solid CO2, 1 g of Raney nickel catalyst and 150 ml of methanol were charged into an autoclave and hydrogen was charged while maintaining the pressure at 20 to 30 Kg/cm2 ·G. Reaction was continued at temperatures of 20° to 25° C. for 8 hours under stirring. Thereafter, the resulting mixture was filtered to remove the catalyst, added with 6 g (0.15 mol) of sodium hydroxide and was subject to distillation. 10.6 g of m-aminobenzylamine of 99.1% in purity by means of gas chromatography was obtained. Yield 86.9%; B.P. 129°-130° C./5 mmHg; M.P. 39°-42° C.
