Comments on "Fundamental properties and intermolecular interaction of triethylene glycol + ethylenediamine aqueous solution for CO2 capture".

• Published Vex data in Table 5 and in Figure 2a are not the same. • Published Redlich-Kister equation does not back-calculated Vex values reported in Table 5. • Published Redlich-Kister equation does not back-calculated Vex values depicted in Figure 2a. • Inconsistencies also noted between tabulated and graphed values of Δ η and Δ G *E. A polemic is given regarding the volumetric properties that Wang and coworkers reported in their published paper. The tabulated excess molar volumes, Vex , reported by the authors are not the same values as graphically depicted in the paper. Our analysis of the experimental data indicated that the tabulated were likely calculated assuming a ternary system, while the graphically depicted values were likely calculated using a pseudo-binary system treatment. Similar inconsistences were noted between several of the tabulated and graphed viscometric properties in the published paper. [ABSTRACT FROM AUTHOR]
