The solubility of hydrogen halides as a function of the basic strength of solvents

The Northern Polytechnic, London, N. 7, G.-B..

Abstract

Data on the solubility of hydrogen halides at different temperatures (50° to — 70°), expressed in moles per mole of solvent are necessary for the accurate description of reaction schemes in the organic chemistry of inorganic non-metal halides such as those of phosphorus, thionyl, silicon and boron (^1–11). The examined compounds which do not contain oxygen or nitrogen show a solubility of HCl not much greater than the ideal solubility based on Raoult’s law. The oxygen containing compounds dissolve HCl to widely different extents apparently depending on the electron donor function of the lone pair electrons on oxygen, influenced greatly by the constitution of the groups attached thereto. The change of solubility with temperature (50° to — 70°) is considerable. Correlation with other base-acid aspects are considered.
