Abstract: The dilution enthalpies of myo-inositol in water and in aqueous sodium halide solutions have been determined with flow-mix-isothermal microcalorimetry at 298.15 K. The enthalpic interaction coefficients in the range of sodium halide 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 sodium halide solutions and absolute values of h2 increase with elongation of radius of halogen anion.
