Bubble point determination for CO2 + Ethanol + Alkanolamines (Monoethanolamine, Diethanolamine, or Triethanolamine) at high pressures

Experimental data from the phase transition of the ternary systems {CO2(1) + [0.25 monoethanolamine(2) + 0.75 ethanol(3)]}, {CO2(1) + [0.25 diethanolamine(2) + 0.75 ethanol(3)]} and {CO2(1)+ [0.25 triethanolamine(2) + 0.75 ethanol(3)]} is reported. A variable volume cell was employed using the stat...
