氢氧化锂和一水合氢氧化锂的溶解度随温度的变化情况 我需要具体的变化情况,越具体越好 还可以增悬赏的啊

这种实验数据国人做得很少,大都是外国人做的.
以下提供外文分析,学化学,你应该看得懂的
The results are interesting in several respects.First,the solubility curve shows a maximum value at about 240" F.and a minimum at about 480" F.and at room temperatwe.A plot of mole fraction of lithium hydroxide content of saturated solution against temperature shows a more abrupt break in the solubility curve than is evident in Figure 2.A sudden drop in solubility occurs near 250" F.and a rapid increase near 500" F.It is likely that the first break in the curve is related to the phase change from the monohydrate to the anhydrous salt.Other salts (such as lithium carbonate,sodium sulfate,and calcium sulfate) also exhibit inverse solubility as a function of temperature.The cause for the rise in solubility at 500" F.is less easily explained.The data also show that increasing the temperature as high as 650" F.did not greatly affect the over-all solubility of lithium hydroxide.For example,values range from a minimum of about 12.7 grams of LiOH per 100 grams of H20 at room temperature to a maximum of only about 17.7 grams at 240" F.In contrast to these results,the solubility values of sodium hydroxide show a rapid and fairly uniform increase as temperatures are raised.Values from the International Critical Tables (I) and from Seidell are presented in Table I for comparison with those for lithium hydroxide obtained in the present study.At 140" F.,the solubility of sodium hydroxide is about 20 times that for lithium hydroxide; at 375" F.,it is amost 35 times greater; at 563" F.,it is about 200 times greater.
