The solubility of lithium aluminum hydride in diethyl ether at the temperatures 0, 20, 25, and 30° is 21.3, 28.4, 28.3, and 26.5% LiAlH4, respectively. The solubility of lithium borohydride at the same temperatures is 1.32, 2.90, 4.80, and 13.4% LiBH4, respectively.
The anomalous variation of the solubility of the two hydrides can be explained by a change in the molecular state of the hydrides: polymerization of lithium aluminum hydride and dissociation of lithium borohydride etherates.
