Densities and Viscosities of Erythritol, Xylitol, and Mannitol in l -ascorbic Acid Aqueous Solutions at T = (293.15 to 323.15) K

The densities and viscosities of ternary solutions (erythritol/xylitol/mannitol + l -ascorbic acid + water) and binary solutions (erythritol/xylitol/mannitol + water), were measured under atmospheric pressure and the temperature range of (293.15 to 323.15) K. The apparent molar volumes ( V φ ), the limiting partial molar volumes ( V φ 0 ) and the limiting partial molar volumes of transfer (Δ tr V φ 0 ) were calculated through densities, respectively. Guimarães equation and extended Jones-Dole equation were applied to correlate the densities and viscosities of erythritol/xylitol/mannitol in l -ascorbic acid aqueous solutions, respectively. The free energy of activation per mole of solvent (Δμ 1 0≠ ) and solute (Δμ 2 0≠ ) were obtained through the viscosity B -coefficients. These significant parameters are helpful to understand the interactions in sugar alcohols + l -ascorbic acid + water ternary solutions.
