Apparent molar volumes and apparent molar heat capacities of aqueous adonitol, dulcitol, glycerol, meso-erythritol, myo-inositol, D-sorbitol, and xylitol at temperatures from (278.15 to 368.15) K and at the pressure 0.35 MPa

Apparent molar volumes V-phi were determined for aqueous adonitol, dulcitol, glycerol, meso-erythritol, myo-inositol, D-sorbitol, and xylitol at temperatures from (278.15 to 368.15) K and at the pressure 0.35 MPa, and apparent molar heat capacities C-p,C-phi of the same solutions were determined at temperatures from (278.15 to 363.15) K at the same pressure. Molalities m/(mol . kg(-1)) of the solutions were in the range (0.02 <= m <= 3.2) for adonitol, (0.02 <= m <= 0.15) for dulcitol, (0.02 <= m <= 5.0) for glycerol, (0.02 <= m <= 3.0) for meso-erythritol, (0.02 <= m <= 0.5) for myo-inositol, (0.02 <= m <= 2.0) for D-sorbitol, and (0.02 <= m <= 2.7) for xylitol. A vibrating tube densimeter was used to obtain solution densities and a fixed-cell temperature scanning calorimeter was used to obtain heat capacities. Values of V-phi and C-p,C-phi for these sugar alcohols are discussed relative to one another and compared to values from the literature, where available. (c) 2006 Elsevier Ltd. All rights reserved.
