Abstract
A process for preparing predominantly noncyclic polyalkylene polyamine compounds is disclosed wherein an alkanolamine compound is reacted with an alkyleneamine compound and ammonia or a primary or secondary amine in the presence of a catalytically effective amount of a Group IIIB metal acid phosphate at a temperature from about 175.degree. to 400.degree. C. under a pressure sufficient to maintain a substantial amount of the ammonia or amine in the reaction zone.
