The reductive animation of ethanol using supported metal catalysts

Silica supported cobalt, nickel and copper are efficient catalysts for the reductive amination of ethanol using ammonia. High selectivity to ethylamine product was obtained between reaction temperatures of 140 and 200°C, between ammonia to ethanol molar ratios ranging from 1 to 4 and between hydrogen to ethanol molar ratios ranging from 2 to 5. Depending on the partial pressures of the ethanol, ammonia and hydrogen feeds, different ethylamine selectivities were obtained. The degree of amine substitution was decreased (i.e. increasing MEA and decreasing DEA and TEA selectivities) by increasing the ammonia partial pressure or by decreasing either the ethanol or hydrogen partial pressures.
