Anionic micelles of sodium dodecyl sulfate (SDS) inhibit reactions of OH-with p-nitrophenyl diphenyl phosphinate (pNPDP) and of OH-, Br-, SCN-, and with methyl naphthalene-2- sulfonate (MeONs). However, first-order rate constants for reactions of OH-, CNS-, and SO,” reach limiting values at high [SDS] under conditions in which the bulk of the substrate is in the micellar pseudophase. Added inert salt speeds reactions of OH-, SCN-, and S032-at ...
