Abstract: There is disclosed a continuous process for making polyethylene polyamines such as diethylenetriamine, triethylenetetramine, etc. comprising the reaction of ethylene oxide with ammonia to produce a mixture of alkanolamines, the amination of the alkanolamines to ethyleneamines, and the reaction of at least a portion of the ethyleneamines thus produced with ethylene dichloride optionally in the presence of ammonia and/or water.
Abstract: There is described a continuous process for the manufacture of ethylenediamine from the products of the reaction of ethylene oxide and ammonia, provision of a continuous recycle stream of monoethanolamine to the products of the reaction of ethylene oxide and ammonia, the amination of such products of the reaction of ethylene oxide and ammonia combined with the monoethanolamine recycle in which the feed stream to the amination reaction zone contains at least 70 weight percent monoethanolamine as well as diethanolamine and triethanolamine, the moles of ammonia provided to the amination reaction exceeds the molar concentration of alcoholic hydroxyl groups present in the amination feed, and the feed to the amination reactor contains at least a 5% increase in the concentration of monoethanolamine over the concentration of monoethanolamine in the reaction product stream from the reaction of ethylene oxide and ammonia.

Abstract: This invention provides for the separation of an amine composition undergoing processing at high temperatures and pressures which amine composition contains volatile components and less volatile components where the volatile components are desirable for further processing and/or utilization and the less volatile components are less desirable for further processing and/or utilization. The separation serves to divide the amine composition into two streams, one which is enriched in the volatile components and the other which is enriched in the less volatile components.
