Abstract

The salvation of solid zinc bromide in contact with diethyl ether solutions has been studied by vapor pressure measurements and solubility determinations from -10 to 35° C. The existence of two solvates, believed to be the dietherate of zinc bromide, ZnBr2, 2(C2H5)2O and the monoetherate of zinc bromide, ZnBr2. - (C2H5)2O, was indicated by the following results: Definite changes in slope occurred in the curves obtained by plotting the logarithm of the vapor pressure of ether for systems of varying mol ratios (mols (C2H5)2O/mols ZnBr2 ) against the reciprocal of the absolute temperature and by plotting the logarithm of the solubility of zinc bromide in ether against the reciprocal of the absolute temperature. These changes in slope, which are caused by changes in the solid phases, appear between 0 and 5° and between 15 and 25°C. Further, analyses of the wet solids in contact with the saturated solutions at 0, 15 and 25° C. indicate that the stable solid phases in equilibrium with the saturated solutions at these temperatures are the dietherate, the monoetherate and the unsolvated zinc bromide, respectively.
