ABSTRACT:
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 at temperatures above the critical temperature of the mixture and at pressures above the critical pressure of the mixture and maintaining the mixture in a single phase having a density of at least 15 lbs./cu.ft. for the time necessary to form an alkanolamine product mixture containing at least about 65% by weight monoalkanolamine.
