Abstract: CONTINUOUS PROCESS FOR PREPARING ALKANOLAMINES A continuous process is provided for preparing alkanolamines having a high yield of monoalkanolamine which comprises continuously reacting a flowing stream of a homogeneous mixture of an alkylene oxide having from two to four carbon atoms and ammonia in a molar ratio of ammonia to alkylene oxide within the range from about 15:1 to about 50:1 maintained in a single supercritical fluid phase in a plug-flow reactor at temperatures above about 100.degree.C and at pressures high enough to maintain the reaction mixture in a single supercritical fluid phase having a density of at least 15 lbs./cu.ft. for the time necessary to form an alkanolamine product mixture containing predominately monoalkanolamine.

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.
