Reaction Steps
4,4′-Methylenebis(benzeneamine) (19.8 g, 0.1 mol), methyl ethyl ketone (20.0 g, 0.28 mol), Pt(S)/C (2.0 g), and water (28.0 g; formed a second phase) were charged into reactor. The reactor was purged 3 times with H2 at 22° C. The reaction mixture was then stirred at 800 rpm at 136° C. under H2 for 2.5 hours. GC showed 100% conversion of 4,4′-methylenebis(benzeneamine), and a 96-97% yield of N,N′-di-sec-butyl-4,4′-methylenebis(benzeneamine).
