  Abstract:  Reductive amination of methyl ethyl ketone (MEK) with ammonia (at ammonia/MEK molar ratios of ~ 14.5) and hydrogen has been performrd at 50 bar and 323-353 K over graphite and charcoal supported noble metal catalysts. Rhodium and platinum based catalysts showed the highest activity in reductive amination of MEK. The rhodium catalysts had high selectivity towards primary amine (sec-butylamine), while the platinum catalysts towards secondary amine (di-sec-dibutylamine). Tertiary amine (tri-sec-butylamine) was not detected in reaction products. The BET area and metal dispersion was found to have a pronounced influence on activity and selectivity.
