- W2011034794 abstract "The hydrolysis of p -nitrophenyl diphenyl phosphate was studied in aqueous solutions containing micelles of cetyltrimethylammonium bromide (CTAB), sodium hydroxide and various concentrations of dimethylsulfoxide (DMSO). Pseudo first-order ( k ψ ) and second-order ( k 2 ) rate constants were determined at 15, 25 and 35°C and activation parameters were also measured. The rate profiles obtained for solutions containing 10–50% DMSO by volume exhibited clear maxima that shifted to higher concentrations of CTAB as a function of DMSO added. For solutions containing 60–80% DMSO by volume there was no maximum in the rate profile and the reaction was inhibited. Solutions containing 90% DMSO by volume exhibited much higher reaction rates and considerably more catalysis. In the absence of surfactant a linear relationship is obtained between log k ψ and the Lorentz function of the dielectric constant of the binary mixtures DMSO–H 2 O. When CTAB is added to the reaction medium there are two different situations. Beyond the formation of the hydrate DMSO·2H 2 O, which inhibits the CTAB micellization, the results are identical to those obtained in the systems with no surfactant. However, in presence of CTAB micelles, the linear relationship between log k ψ and f ( ε ) was quite different from that in the other two cases. These results show that a macroscopic property such as the dielectric constant of the medium may be used to describe the effect of DMSO on the hydrolysis rates either in absence of surfactant or when this is dissolved as the monomer, but not in the presence of micellized surfactant." @default.
