The kinetics of the reaction of the 4-nitrophenyl esters of diethylphosphoric and 4-toluenesulfonic acids with HO(-) and HOO(-) anions in microemulsions of the "oil-in-water" type was studied. It was shown that the reactivity of the HOO(-) anion depends on the nature of the detergent forming the microemulsion and decreases in the order cetyltrimethylammonium bromide > Triton X-100 > sodium dodecyl sulfate. It was established that concentration of the reagents on the surface of the microdrops leads to an increase of 2-3 orders of magnitude in the rate during the transition from aqueous solutions to the microemulsion.
