Abstract In this work, the effect of some deep eutectic solvents (DESs) based on choline chloride on the thermodynamic and transport properties of D-fructose in aqueous solutions was investigated. Using the vapor-liquid equilibrium (VLE) data, water activity (aw), osmotic coefficient and vapor pressure data were obtained. The performance of different local composition models such as Wilson, e-NRTL, and UNIQUAC for correlating of these data have been examined. The calculated negative values of Gibbs free energies of transfer ( Δ G t r i ) indicate favorable interaction of DESs with D-fructose. Further, the standard partial molar volumes V φ 0 , partial molar isentropic compressibility K φ 0 , viscosity B-coefficient and molar refractions RD for the solutions have been calculated from the measured density and speed of sound, viscosity and refractive index data at T = (288.15 to 318.15) K. Interaction volume V int and cavity volume Vcav have been computed from scaled particle theory (SPT) to probe solute-solvent interactions. The viscosity B-coefficients was used to discuss structure-making tendency of the solutions studied.

基于氯化胆碱的低共熔溶剂对 D-果糖在水溶液中的热力学和传输性质的影响

摘要 在这项工作中，研究了一些基于氯化胆碱的低共熔溶剂 (DESs) 对 D-果糖在水溶液中的热力学和传输性质的影响。使用汽液平衡 (VLE) 数据，获得了水活度 (aw)、渗透系数和蒸汽压数据。已经检查了不同局部成分模型（例如 Wilson、e-NRTL 和 UNIQUAC）用于关联这些数据的性能。计算出的吉布斯转移自由能 (Δ G tri ) 的负值表明 DES 与 D-果糖的良好相互作用。此外，溶液的标准偏摩尔体积 V φ 0 、偏摩尔等熵压缩率 K φ 0 、粘度 B 系数和摩尔折射 RD 已经从测量的密度和声速计算出来，T = (288.15 至 318.15) K 时的粘度和折射率数据。相互作用体积 V int 和腔体积 Vcav 已根据比例粒子理论 (SPT) 计算，以探测溶质 - 溶剂相互作用。粘度 B 系数用于讨论所研究溶液的结构形成趋势。
