Abstrakt: Enthalpies of dilution of aqueous systems containing trioxane, and trioxane with each of mannitol, inositol and cyclohexanol have been determined at 25°C. The data have been treated in terms of the Savage-Wood additivity principle and, in conjunction with literature data on ether compounds a revised estimate of the pairwise group-interaction enthalpy for CH2/−O− and a first estimate for CHOH/−O− are presented. Systems of saccharides and saccharides with alcohols do not conform to the Savage-Wood principle and an explanation in terms of the specific hydration properties of saccharides is offered.
