Solubility determinations of zinc bromide in diethyl ether were made over the temperature range -20 to +35/sup 0/. The existence of two etherates of zinc bromide has been further substantiated and their transition points determined more precisely: probably zinc bromide monoetherate, ZnBr/sub 2/.(C/sub 2/H/sub 5/)/sub 2/O stable below +16-17/sup 0/, and zinc bromide dietherate, ZnBr/sub 2/.2(C/sub 2/H/sub 5/)/sub 2/O which decomposes above +4/sup 0/. The differential heats of solution at saturation were calculated over the entire temperature range studied averaging 3.5 kcal/mole for the monoetherate and 0.60 kcal/mole for the unsolvated zinc bromide. The dietherate gave a value of 6.2 kcal/mole at 0/sup 0/ falling to 4.3 kcal/mole at about -8/sup 0/ and rising to 10.5 kcal/mole at -20/sup 0/.
