WebSodium hypochlorite solutions have been used in wound care for a hundred years and are familiar to practitioners as Dakin's solution. In the last 15 years more advanced hypochlorous acid solutions based on … WebFactors affecting reaction kinetics. The Dakin oxidation has two rate-limiting steps: nucleophilic addition of hydroperoxide to the carbonyl carbon and [1,2]-aryl migration. Therefore, the overall rate of oxidation is dependent on the nucleophilicity of hydroperoxide, the electrophilicity of the carbonyl carbon, and the speed of [1,2]-aryl migration. . The …

In this study, the effect of the amount of UHP was investigated (Figure 2). The yield of Dakin reaction increased when the amount of UHP was increased from 0.4 to 1.2 equiv.; after that, the yield did not improve markedly. Therefore, 1.2 equiv. of UHP was selected for this lipase-mediated Dakin reaction.
