The isotherms of MBr-AlBr3-Et2O (M=Na, K, Rb) at 25° are characterized by the crystallization branches of MBr and the AlBr3·Et2O etherate. The successive crystallization of AlBr3·Et2O, CsAlBr4 and CsBr was established in the CsBr-AlBr3-Et2O system at 25°.
The isotherm of KBr-AlBr3-C7H8 at 25° has the crystallization branches of Al2Br6·C7H8, KAl2Br7, KAlBr4, and KBr. A stratification region and the crystallization fields of Al2Br4·C7H8, Rb(Cs)Al2Br7 and Rb(Cs)Br were established for the Rb(Cs)Br-AlBr3-C7H8 systems.
