Abstract
A process for selectively preparing predominantly non-cyclic polyalkylene polyamine compounds is disclosed wherein an alkylene polyamine compound is contacted with a hydroxy compound in the presence of a catalytically effective amount of a substance of arsenic, antimony or bismuth at a temperature of from 250.degree. to 300.degree. C. under a pressure sufficient to maintain the reaction mixture essentially in liquid phase. The polyalkylene polyamine thus formed is recovered from the reaction mixture.
