摘要
通过实验,研究调节剂对改进混合溶剂热力学平衡特性的作用,阐明应该综合考虑氢键、疏溶作用、分子极性和色散力等分子间相互作用力、溶解度和沸点来选择调节剂.并指出稀释剂在混合溶剂中起着减小粘度、加快传质速度的作用,改进了萃取剂的动力学特性.
From experiments, the effect of modifiers for the improvement of thermodynamic equilibrium properties of mixed solvents is explained. The selection of modifier should be considered comprehensively with hydrogen bond, solvophobic, mo- lecular polar, solubility, boiling point. The diluent in the mixed solvents decreases the viscosity, makes mass transfer fast, improves the kinetic properties of extractant.
