摘　　要：实验测定了不同温度条件下KCl、Rb Cl在冰乙酸中的溶解度,实验结果表明KCl、Rb Cl在冰乙酸中的溶解度均随温度的升高而增大,且Rb Cl的溶解度明显大于KCl的溶解度.并测定了KCl、Rb Cl在不同配比冰乙酸-水溶液中的溶解度,并得到其盐析率.结果表明:冰乙酸对KCl、Rb Cl都具有较强的盐析作用,但随着剂水比增加,KCl的盐析率逐渐高于Rb Cl.The solubility of rubidium chloride and potassium chloride in glacial acetic acid were measured at different temperatures. The experiment results showed that the solubility of rubidium chloride and potassium chloride in glacial acetic acid increased with the rise of temperature, and the solubility of rubidium chloride significantly higher than the solubility of potassium chloride. The solubility of rubidium chloride and potassium chloride in different ratio glacial acetic acid-water were measured and the salting-out rates were calculated. The results showed that glacial acetic acid had strong salting-out effect on rubidium chloride, potassium chloride. However, with the proportion of water rise, the salting-out rate of the influence of potassium chloride became higher than that of rubidium chloride.
