Solubility of lithium aluminum hydride and lithium borohydride in diethyl ether

  • Published:
Bulletin of the Academy of Sciences of the USSR, Division of chemical science Aims and scope

Conclusions

  1. 1.

    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.

  2. 2.

    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.
