Solubility of CO2 in aqueous 2‑amino‑1, 3‑propanediol (Serinol) at elevated pressures

In this work, aqueous 2‑amino‑1, 3‑propanediol solution (serinol) was investigated as a potential solvent for CO2 capture from different gas streams. Prior to CO2 solubility experiments, a qualitative prediction technique was performed on serinol to ensure its potentiality as a CO2 capture solvent....
