Excess properties and viscous flow thermodynamics of the binary system 1,2-ethanediamine+triethylene glycol at T=(298.15, 303.15, 308.15, and 313.15) K for CO2 capture

Heat Capacity, Density, Vapor Pressure, and Enthalpy of Vaporization of Isoamyl dl-Lactate

“…Density. The isoamyl DLlactate density was measured using a Gay-Lussac pycnometer 16 with 25 mL bulb capacity (Shanghai Loikaw Instrument Co., Ltd). The pycnometer containing the sample was placed in a thermostatically controlled oil bath for at least 20 min, and the bath temperature was controlled within ±0.05 K. The pycnometer was calibrated before measurement using 1nonanol at different temperatures of T = (273.15−473.15) K, and the results are given in the Supporting Information (Table S1 and Figure S1).…”

Gas–liquid equilibrium data for mixture gas of carbon dioxide + nitrogen in 1,2-ethanediamine + triethylene glycol aqueous solution

“…Because of the presence of two amino groups in EDA, it exhibits a high CO 2 loading capability. Our previous work [19] indicated that TEG has multiple hydrogenbonding sites, which can form multiple hydrogen bonds with EDA. Moreover, TEG is a promising medium for CO 2 capture process because of its high thermostability, low-to-moderate vapour pressure below T = 373 K and relatively low toxicity.…”

“…In the previous work, we have [19] disclosed the density and viscosity data of the system EDA + TEG at T = 293. 15 .87 kPa, and on optimising the composition of aqueous EDA + TEG solution for the CO 2 capture processes.…”
