ABSTRACT:
A process for preparing noncyclic polyalkylene polyamine compounds is disclosed wherein ammonia, an alkylene polyamine compound and an alkanolamine compound are reacted in the presence of an effective amount of a phosphorus-containing substance or a salt of a sulfur-containing substance or its corresponding acid at a temperature from about 200.degree. to 350.degree. C. under a pressure sufficient to maintain the reaction mixture essentially in liquid phase. The polyalkylene polyamines thus formed are recovered from the reaction mixture.
