Thermodynamic Modeling of Alcohol/Carbohydrate-Based Aqueous Two-Phase Systems
摘要
Solubility data were experimentally acquired at ambient temperature using alcohols (2-propanol and 2-butanol) + carbohydrates (glucose and sucrose). The tie-lines were also obtained for solvation data. Additionally, the Othmer–Tobias and Bancroft equations were utilized to match tie-line data and to judge the reliability of the computational approach and related tie-line data. Also, experimental results were correlated with the thermodynamic UNIQUAC and NRTL models, and the precision of the NRTL model was higher than that of the UNIQUAC model.
