Solubilities of caesium hexachlororhenate(IV), hexabromorhenate(IV), and tetraoxorhenate(VII) in alcohol–water mixtures, and their relation to cosolvent characteristic volume

Abstract

Solubllities of Cs2[ReCl6] in methanol–, ethanol–, and t-butyl alcohol–water mixtures, and of Cs2[ReBr6] and Cs[ReO4] in methanol–water, mixtures, are reported. Correlation of these solubilrties with various solvent and solubllity parameters is discussed; a simple correlation of solubilities with solvent composition and cosolvent characteristic volume is remarkably satisfactory.
