摘要：
Solubilities are reported of the calcium sails of a series of dicarboxylic acids, HO2C(CH2)(n)CO2H, with n = 0, 1, 2, 4, 8 and 12, and of cyclobutane-1,1-dicarboxylic acid in methanol-water mixtures containing 0-80% methanol. From these results, and known values for transfer chemical potentials for Ca2+, transfer chemical potentials for the dicarboxylate anions have been calculated. The derived trends are discussed in terms of the hydrophilic/lipophilic properties of the anions and consequent preferential solvation.
