摘要
Experimental data on the solubility of D-glucose,D-fructose and sucrose in the mixed solvents com-posed of water and ethanol from 273.2 to 293.2 K were determined.The solubility of D-glucose,D-fructose and sucrose decreased as the ethanol content increased in the mixed solvent.The solubility of D-glucose,D-fructose and sucrose decreased with decreasing equilibrium temperature.The modified UNIQUAC model,S-UNIFAC model and mS-UNIFAC model were applied to predict the solid-liquid equilibria.The prediction results were compared and discussed.Better prediction accuracy was generated using the modified UNIQUAC model.
D 葡萄糖的溶解度上的试验性的数据, D 果糖并且在从 273.2 ~ 293.2 K 由水和乙醇组成的混合溶剂的蔗糖被决定。D 葡萄糖的溶解度, D 果糖并且蔗糖作为内容在混合溶剂增加了的乙醇减少了。D 葡萄糖的溶解度, D 果糖并且蔗糖与减少的平衡温度减少了。修改 UNIQUAC 模型, S-UNIFAC 模型和 mS-UNIFAC 模型被使用预言稳固液体的 equilibria。预言结果被比较并且讨论。更好的预言精确性用修改 UNIQUAC 模型被产生。
