摘要
The Ostwald coefficients L2,1 of He, Ne, Ar, Kr, Xe, N2, O2, CH4, CF4, and SF6 dissolved in several homologous alkan-1-ols, n-ClH2l+1OH,1 less-than-or-equal-to l less-than-or-equal-to 11, have been determined at 298.15 K and atmospheric pressure. Altogether, 102 gas/liquid systems were investigated. The medium precision apparatus (about +/-0.5%) was of the Ben-Naim/Baer type, similar to our recently published design. Data reduction is presented in some detail, including the estimation of auxiliary quantities, such as second virial coefficients and partial molar volumes at infinite dilution. The effect of chain length l is shown, and several correlations between L2,1 (and/or the derived Henry fugacity H-2, H-1) and appropriate molecular and/or bulk properties of the gases and solvents are discussed.
