description The invention belongs to the technical field of preparation of gas absorbents, and particularly relates to a compound solvent screening method based on thermodynamic properties of a eutectic solvent. The CO2 absorbent comprises a eutectic solvent and an organic solvent additive in a mass ratio of 1: (1-4). The compound solvent screening method based on the thermodynamic property of the eutectic solvent specifically comprises the following steps that firstly, the eutectic solvent is dissolved in 49 organic solvents, the dissolution condition is observed, the three-dimensional solubility parameter of the eutectic solvent is calculated through the HSPiP technology, and the three-dimensional solubility parameter of the eutectic solvent is calculated through the HSPiP technology; according to the dispersion solubility parameter, the polarity solubility parameter and the hydrogen bond solubility parameter of the solvent to be selected, the solvent which is completely soluble with the deep eutectic solvent, high in
