Abstract
This invention pertains to the production of aminoethylethanolamine in high selectivity by the intermolecular condensation of monoethanolamine with itself. Selective intermolecular condensation is achieved by reacting monoethanolamine with itself at a temperature from 175.degree.-275.degree. C., and a pressure from 50-400 psig, said reaction being carried out in the presence of a rare earth metal or a strontium metal hydrogen phosphate.
