Abstract
Improvements in catalyst systems and associated processes for the conversion of glycolaldehyde to monoethanolamine are disclosed. The catalyst systems exhibit improved selectivity to this desired product and consequently reduced selectivity to byproducts such as diethanolamine and ethylene glycol. These beneficial effects are achieved through the use of acids, and particularly Lewis acids, as co-catalysts of the reductive amination reaction, in conjunction with a hydrogenation catalyst.
