Solubility measurement data of carbon dioxide (CO2) in the ionic liquid 1-butyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide [BMIM][NTf2] at T = (273.15 to 413.15) K, and pressures up to p = 4.5 MPa are presented. The measurements were carried out using the isochoric method as a function of temperature ranging from T = (413.15 to 273.15) K in decrements of DT = 20 K at selected four different pressure steps ranging from around P = 4.5 MPa to around P = 0.5 MPa. The temperature dependency of Henry s law constant was calculated and the average deviation of the Henry s law constant is always better than +-1%. Thermodynamic properties of solution such as the Gibbs free energy of solvation, the enthalpy of solvation, the entropy of solvation, and the heat capacity of solvation were calculated to evaluate the solute solvent molecular interactions.
