Abstract
Partial molar heat capacities at infinite dilution, C(p,2)infinity, ha ve been determined calorimetrically for D-mannitol and D-sorbitol in w ater, dimethyl sulfoxide and formamide, at 298.15 K. The C(p,2)infinit y values obtained, which are similar for the three solvents, are much higher than the heat capacities for the pure compounds. The large DELT AC(p)infinity values for the dissolution process are believed to be pa rtly due to the existence of several rotamers in solution. Sorbitol se ems to be more sensitive than mannitol to specific solvent effects.
