Abstract

The relative rates of the micelle-catalyzed/inhibited aquation reactions of the complexes: Fe(Ph2Phen), Fe(Me2Phen) and Fe(MePhen were investigated in ethylene glycol, water and aqueous acetone. The pseudo first oder rate constant, K vs (Triton X-100) profiles reveal that at all the (TX-100) concentration ranges considered for ethylene glycol and water, and for aqueous aceton at (Triton X-100) >/minus 15.00(%v/v) the pseudo first order rate constant, k values follow the order: Fe(Me4 Phen)> Fe(ph2Phen) , suggesting a substrate binding strength of the order: Fe(Me2Phen) rates of the complexes in ethylene glycol and water fall within the same range of 0.0 - 100.0 x 10 S while the aquation rates in aqueous acetone are generally about 10 cubic faster. These observations have been attributed to evolution of different micellar types and aquation mechanisms.UNISWA Research Journal of Agriculture, Science and Technology Vol. 4 (1) 2000: pp 113-118
