実験手順
4,4′-Methylenebis(benzeneamine) (1.98 g, 10 mmol), acetone (10.0 g, 172 mmol), Pt(S)/C (0.2 g), and toluene (50.0 g) were charged into reactor. The reactor was purged 3 times with 110 psig (8.60×105 Pa) of H2 at 22° C. The reaction mixture was then stirred at 60° C. under 110 psig (8.60×105 Pa) of H2 for 2 hours. GC (conditions: 180° C./5 miminutes/10° C.-minutes rate/270° C./RT=9.37 minutes) showed 100% conversion of 4,4′-methylenebis(benzeneamine), and a 97% yield of N,N′-diisopropyl-4,4′-methylenebis(benzeneamine). The structure of the product was confirmed by GC-MS. No tertiary diamine was detected either by GC or by GC-MS.
