- NMR Characterization of H2o2 Hydrogen Exchange
The specific acid-, base- and water-catalyzed HX rates at 2 °C were measured to be 2.1 × 10 7, 6.1 × 10 9, and 1.4 × 10 −1 M −1 s −1, respectively, which result in a minimum HX rate at pH 6.2. Furthermore, the exchange is accelerated by general acid/base catalysis.
A technique utilizing 1H NMR spectroscopy has been developed to measure the concentration of hydrogen peroxide from 10 (-3) to 10 M. Hydrogen peroxide produces a peak at around 10-11 ppm,...
