extraction equilibrium - Opis:
- The extraction equilibria of hypophosphorous, phosphorous and phosphoric acids with tri-n-octylamine as an extractant in toluene were measured at 303K. Under these conditions, undissociated acid (A’) reacts with the amine (B) to form various complexes in toluene. The complexes formed and equilibrium constants were estimated by a graphical analysis method. The complexes formed in these systems were found to be A’nB type species for hypophosphorous acid, A’nBm type species for phosphorous acid, (A'B)n type species for phosphoric acid, respectively. The experimental results could be explained by reaction models and equilibrium constants for each acid.
