N2 - The mutual solubilities of anhydrous hydrogen fluoride (AHF) and n-pentane, n-hexane, and n-heptane have been measured under equilibrium pressure conditions of the mixed vapors at five temperatures between -25° and 40°. These data, and literature data for propane, n- and isobutane, and octane, are compared with the corresponding data for water and hydrocarbons. Contrary to the latter, the solubilities of hydrocarbons in AHF have positive standard enthalpies, and the solubility of AHF in hydrocarbons decreases with their increasing size. The treatments of Hildebrand and Scott and of Nemethy and Scheraga for the mutual solubilities with water were examined as to their applicability to the AHF systems. A treatment following that of Prigogine and Defay for associated liquids is shown to apply better, and leads to an estimate of the fraction of monomeric hydrogen fluoride in AHF of from 0.1 to 1% at 20°.
