SOLUBILITY OF GASES IN BUTANOLS .1. SOLUBILITIES OF NONPOLAR GASES IN1-BUTANOL FROM 263.15 TO 303.15 K AT 101.33 KPA PARTIAL-PRESSURE OF GAS

Solubility measurements 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 1-butanol were c arried out at 263.15, 273.15, 283.15, 293.15, and 303.15 K and partial pressure of gas of 101.33 kPa. Standard changes in thermodynamic func tions for the solution process at 298.15 K (Gibbs energy, enthalpy and entropy) are derived from the experimental values of the solubility o f gases and its variation with temperature. Lennard-Jones 6,12 pair po tential parameters and the dependence of the effective hard-sphere dia meter with respect to the temperature for 1-butanol have been estimate d using the equations of scaled particle theory (SPT). Making use of S PT in the reverse direction, i.e., starting from the potential paramet ers found through it, theoretical solubilities and thermodynamic funct ions for the solution process have been calculated and compared with t he experimental values.
