摘      要：The potassium acetate solutions are new potential working fluids for the closed-type reverse electrodialy-sis(RED)power generation system driven by thennal *** this paper,the solubilities of potassium acetate in water,2,2,2-trilluoroethaiiol,ethanol and their binary mixtures were measured by using the laser dynamic method over the temperature range of 288.15 to 333.15 K under atmospheric *** results indicate that the solubility of potassium acetate solution is influenced by both the solvent components and solution temperature ***,it is found that the measured solubility data of the potassium acetate-water-2,2,2-trifluoroethanol solutions as per the laser dynamic method are sliglitly larger than that of the data obtained as per the static ***,five correlation models,including the Van?t Hoff model,Modified Apelblat model,Yaws model,A/z model and Modified Apelblat-Jouyban-Acree model,were used to correlate the measured solubility data of those potassium acetate solutions,with the relative standard deviations within 0.23%to 1.58%.
