SOLUBILITY OF GASES IN BUTANOLS .2. SOLUBILITIES OF NONPOLAR GASES IN2-METHYL-1-PROPANOL FROM 263.15 TO 303.15 K AT 101.33 KPA PARTIAL-PRESSURE OF GAS

Solubilities of 15 nonpolar gases (He, Ne, Ar, Kr, Xe, H-2, D-2, N-2, O-2, CH4, C2H4, C2H6, CF4, SF6 and CO2) in 2-methyl-1-propanol have be en measured at 263.15, 273.15, 283.15, 293.15, and 303.15 K and at the partial pressure of gas 101.33 kPa. Standard changes in the thermodyn amic properties for the solution process (enthalpies, entropies and Gi bbs energies) at 298.15 K have been derived from the experimental data . The scaled particle theory (SPT) has been applied in order to estima te the Lennard-Jones 6,12 pair potential parameters at 298.15 K and th e dependence of the effective hard-sphere diameter on the temperature for 2-methyl-1-propanol. Theoretical solubilities and values for the t hermodynamic functions have been calculated using the SPT in the rever se direction starting from the potential parameters. Results for 2-met hyl-1-propanol have been compared with those corresponding to 1-butano l.
