ABSTRACT:
Lower trialkanolamines such as triethanolamine and triisopropanolamine are converted to the corresponding mono- and dialkanolamine by reacting with ammonia at about 150.degree. C.-275.degree. C. under superatmospheric pressure in the presence of a hydrogenation catalyst. The process is particularly useful for the recovery of alkanolamine values from still bottoms of alkanolamine production processes.
