ABSTRACT:
A process is provided for preparing predominantly linear polyalkylene polyamines which comprises reacting ammonia or an alkyleneamine compound having two primary amino groups or mixtures thereof with an alcohol or an alkanolamine compound having a primary amino group and a primary or secondary hydroxyl group or mixtures thereof in the presence of a derivative of carbonic acid at a temperature at which the reaction will proceed under pressures sufficient to maintain the reaction mixture substantially in a liquid phase.
