Joint solubility of lithium and aluminum bromides and iodides in ether and toluene at 25

1. The method of constructing the solubility isotherms was used to study the systems LiHal-AlHal3-Solv at 25°, where Hal=Br or I, and Solv=diethyl ether or toluene. 2. The LiBr-AlBr3-Et2O isotherm at 25° is characterized by the crystallization of the AlBr3·Et2O solvate and LiBr. 3. The equilibrium in the system LiBr-AlBr3-C7H8 is determined by the successive crystallization of 2AlBr3 · C7H8, AlBr3, LiAlBr4, and LiBr. 4. Three solvates crystallize in the system LiI-AlI3-Et2O at 25°: Lil·Et2O, LiAlI4 · Et2O, and AlI3 · Et2O; the solubility of LiI and AlI3 in ether is respectively 29.3 and 30.3 mole %. 5. The LiI-AlI3-C7H8 isotherm at 25° has the crystallization branches of LiI, LiAII4, and AlI3; the solubility of aluminum iodide in toluene is 2.1 mole %.
