Ethanolamine is subjected to reductive amination in a continuous process to produce diethylenetriamine with less than 10 weight percent piperazine contained in the reaction products. The reductive amination conditions include the use of a catalyst, an ethanolamine feed rate of at least about 400 kilograms of ethanolamine per hour per cubic meter of catalyst, and a temperature sufficient to react between about 35 and 60 percent of the ethanolamine fed.
