ABSTRACT

The enthalpies of dilution of myo-inositol in aqueous solutions of alkali metal salts and alkaline earth metal salts have been determined with flow-mix isothermal microcalorimetry at 298.15 K. The enthalpic interaction coefficients in the range of salt solutions have been calculated according to the McMillan-Mayer theory. The results show that enthalpic pairwise interaction coefficients h2 of myo-inositol are negative in aqueous alkali metal salt and alkaline earth metal salt solutions. The absolute value of h2 becomes small with an elongation of the radius of the alkali metal cation while it becomes large with an elongation of the radius of the alkaline earth metal cation. The results are discussed in terms of the different metallic ions, interactions of solute with solute and solute with solvent.
