Comment on the paper of Hosein Ghaedi et al. entitled “Measurement and correlation of physicochemical properties of phosphonium-based deep eutectic solvents at several temperatures (293.15 K-343.15 K) for CO2 capture”

The usability and correctness of the internal pressure values as calculated by Ghaedi et al. (2017) are critically discussed. The comparison with the data based on thermodynamic relationships shows that their results are misleading.
