文摘

The density of (30 mass % potassium carbonate + 3 mass % sarcosine) and (30 mass % K₂CO₃ + 3 mass % pipecolic acid) were measured for temperature ranging from (303 to 353) K. The experimental data are presented with an aqueous solution of 30 mass % K₂CO₃. The solubility of the aqueous blended solution was measured at (353, 373, and 393) K over CO₂ partial pressure ranging from (0.1 to 1500) kPa. The results are shown with the solubility of CO₂ in 30 mass % K₂CO₃. Due to the fact that the amino acid has acidic character, the CO₂ solubility of aqueous blended solutions is slightly lower than that of the solution of 30 mass % K₂CO₃.
