Abstract

The rate constants for reactions of OH-with 2, 4-dinitrochlorobenzene (DNCB), 2, 4- dinitrochloronaphthalene (DNCN), and p-nitrophenyl diphenyl phosphate (pNPDPP) in micellized cetyltrimethylammonium hydroxide (CTAOH) do not conform to the pseudophase ion-exchange model. The rate constants do not become constant when substrates are fully micellar bound and increase on addition of NaOH. However, with the more hydrophobic ...
