Densities and Viscosities of Sugar Alcohol Aqueous Solutions

Abstract

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 %.

Delivery of High Solubility Polyols by Vibrating Mesh Nebulizer to Enhance Mucociliary Clearance

“…(39) Increasing viscosity decreases droplet size, but is countered by prolonged treatment time as seen for both nebulizers in Tables 3 and 4. Further, nebulization slows down or completely halts at a viscosity value dependent on the mesh nebulizer.…”

Mannitol Delivery by Vibrating Mesh Nebulisation for Enhancing Mucociliary Clearance

“…Aerosol output was characterised by frequent periods of intermittent nebulisation that contributed to a lengthy treatment time. The addition of mannitol was expected to increase both fluid surface tension and viscosity 57–59. With the addition of 150 mg/mL mannitol to deionised water, median droplet size decreased from 13.79 to 11.27 μm, but was still clearly outside the respirable range (<5–6 μm) 52.…”

Foaming, emulsifying and rheological properties of extracts from a co-product of the Quorn fermentation process

“…Fungal rhamnolipids are used as foaming and emulsifying agents [42]. Several sugar alcohols, which are characterised by their viscosifying properties [43], were identified. A range of fatty amides including fatty acyl ethanolamines was detected.…”
