| Abstract: | Partition of the VO(2)L(-) complex (formed from vanadium(V) and PAR 4-(2-pyridylazo)-resorcinol]) between water and a chloroform solution of TOMACl (trioctylmethylammonium chloride) has been studied. The V-PAR-TOMACl complex extracted into the chloroform phase was found to be 1:1:1 in composition. The extraction equilibrium constant is log K = 4.0 +/- 0.1. |
