Abstract

A process is provided for preparing alkanolamines having a high yield of monoalkanolamine which comprises reacting in a reaction mixture an alkylene oxide having from two to four carbon atoms with ammonia in a molar ratio of ammonia to alkylene oxide within the range from about 15.1 to about 50.1 at temperatures above the critical temperature of the reaction mixture and at pressures above the critical pressure of the reaction mixture and high enough to maintain the reaction mixture at sufficiently high fluid densities.
