Gibbs-Helmholtz equation, solubility

The solubility of a solute in a supercritical fluid can be quantitatively estimated using Giddings theory, which relies on differences between the Hildebrand solubility parameters for the SF and solute concerned. Solubility in a supercritical fluid can be understood by examining the Gibbs-Helmholtz equation ... [Pg.285]

Temperature Effect The effect of temperature on the value of the partition ratio can vary greatly from one system to another. This depends on how the activity coefficients of the components in each phase are affected by changes in temperature, including any effects due to changes in mutual solubility with temperature. For a given phase, the Gibbs-Helmholtz equation indicates that... [Pg.1709]

In this form the temperature dependence of the solubility is not explicit because AGfus is itself a function of T. This expression can also be written in terms of the enthalpy of fusion, Afffus, by differentiating it with respect to T and using the Gibbs-Helmholtz equation d AG/T)/dT — —AH/T (5.2.14) ... [Pg.211]
