Solubilities of 15 non-polar gases (He, Ne, Ar, Kr, Xe, H-2, D-2, N-2, O-2, CH4, C2H4, C2H6, CF4, SF6 and CO2) in 2-butanol have been measured at 263.15, 273.15, 283.15, 293.15, and 303.15 K at gas partial pressure 101.33 kPa. Standard changes of Gibbs energy for the solution process at 298.15 K have been determined from experimental data and the corresponding standard changes of enthalpy and entropy have also been calculated using the variation of solubilities with temperature. The Lennard-Jones 6,12 pair potential parameters have been estimated for the solvent through the Scaled Particle Theory (SPT). The parameters obtained have been compared with those corresponding to 1-butanol and 2-methyl-1-propanol.
