WebSep 10, 1998 · This example shows the boehmite catalyzed reversion of H4EAQ and H4EAQ-EO to EAQ in the neutral phase, i.e., after extraction of the hydrogen peroxide, but before hydrogenation. Complete reversion of H4EAQ-EO was observed in all but one experiment. In addition, in every experiment part of the H4EAQ-EO was converted to EAQ. WebAbstract: In this paper, we developed a reversed-phase high performance liquid chromatography for the quantitative analysis of anthraquinone in hydrogen peroxide working solution.
