Abstract

DSC and DTA were used to construct the phase diagram of the water–monoethanolamine (MEA) system in a temperature range of 133–313K. The phase diagram is characterized by the supercooling of a liquid phase and devitrification at ∼150K. MEA·2H2O (congruently melted at 238K), MEA·H2O (incongruently melted at 248K), and limited solid solutions of MEA in H2O were detected.
