The densities and viscosities of ternary solutions (erythritol/xylitol/sorbitol/maltitol + vitamin B6 + water) were measured at 293.15 K, 303.15 K, 313.15 K, 323.15 K and atmospheric pressure. The experimental densities were correlated in terms of the Guimar茫es equation, and the apparent molar volumes (V蠁), the limiting partial molar volumes (V蠁0), and the limiting partial molar volumes of transfer (螖trV蠁0) were calculated through the densities. The experimental viscosities were correlated according to the extended Jones鈥揇ole equation to obtain the viscosity B coefficients, and the free energies of activation per mole of solute (螖渭20鈮?/sup>) and per mole of solvent (螖渭10鈮?/sup>) were calculated. These obtained thermodynamical properties and transport properties of multicomponents are useful to understand the structural change and strong solute鈥搒olvent interaction in the ternary solutions (sugar alcohols + vitamin B6 + water).
