Аннотация: 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.

Ключевые слова: monoethanolamine (ethanolamine), water, phase diagram, differential scanning calorimetry, differential thermal analysis.
