Densities and Viscosities of Sugar Alcohol Aqueous Solutions

In this paper, the densities and the viscosities for butane-1,2,3,4-tetrol (erythritol), (2S,3R,4R,5R)-hexane-1,2,3,4,5,6-hexol (sorbitol), (2R,3R,4R,5R)-hexane-1,2,3,4,5,6-hexol (mannitol), (2R,3R,4S)-pentane-1,2,3,4,5-pentol (xylitol), and 2-(hydroxymethyl)-6-[4,5,6-trihydroxy-2-(hydroxymethyl)oxan-3-yl]oxyoxane-3,4,5-triol (maltitol) aqueous solutions of various mole concentrations have been determined at T = (293.15, 303.15, 313.15, and 323.15) K. The experimental data for the viscosities of sugar alcohol aqueous solutions present a nonlinear relation to the temperature or concentration. The exponential model was used to correlate the experimental data for viscosities, with the maximum average deviation of 3.7 %. The experimental data for the densities of sugar alcohol aqueous solutions show a linear relation to the temperature or concentration considerably well. The linear equation was used to correlate the data for densities, and the maximum average deviation between the experimental data and the calculated values is 0.056 %.
