Title: Solubility of xylitol and sorbitol in ionic liquids - Experimental data and modeling
Issue Date: 2012
Abstract: Solubility of biomass-derived compounds in ionic liquids is an important parameter for the design offuture processes incorporating ionic liquids as solvents for biorefining. Sugar alcohols such as sorbitoland xylitol are carbohydrate derivatives which have been identified as building blocks for biorefining.Therefore, in this work the solubility of these two sugar alcohols was measured experimentally withinthe temperature range of 288 K to 433 K, in three ionic liquids: [emim][EtSO4], Aliquat336(N-Methyl-N,N-dioctyloctan-1-ammonium chloride), and Aliquat[NO3] (N-Methyl-N,N-dioctyloctan-1-ammonium nitrate). In addition, the densities of the ionic liquids were also measured and correlated.Local composition models such as NRTL, e-NRTL, and UNIQUAC were successfully applied to representthe experimental solubility data. The thermodynamic functions of dissolution were also calculated fromthe experimental data.
