Abstract / Full Text

The extraction equilibria in undecan-1-ol–HCl (2.5–9.45 M) systems in the absence and in the presence of 0.55 M FeCl3 were studied. The distribution coefficients of HCl, as well as of HCl and Fe(III) for simultaneous extraction into undecane-1-ol were measured. Two mathematical models including the material balance equations on the basis of the extraction of HCl and FeIII ions by the hydration– solvation mechanism were proposed. The compositions of extracted complexes were studied.
