Production of non cyclic polyalkylene polyamines.

摘要

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° to 400°C under a pressure sufficient to maintain a substantial amount of the ammonia or amine in the reaction zone.
