The kinetics of the reaction between 1,2,3-trihydroxybenzene (pyrogallol) and O2 (autoxidation) have been determined by monitoring the concentration of dissolved dioxygen with a polarographic oxygen electrode. The reaction is carried out in pseudo-first-order excess pyrogallol, 25掳C, 0.08 M NaCl...
The Co-MOF not only acted as a catalyst to accelerate the generation of reactive oxygen species in the CL reaction, but also worked as an emitter to further enhance the CL. Based on the Co-MOF-NaIO4-H2O2 system, a highly sensitive CL analysis method was established ...
(Elements & Compounds) a white lustrous crystalline soluble phenol with weakly acidic properties; 1,2,3-trihydroxybenzene: used as a photographic developer and for absorbing oxygen. Formula: C6H3(OH)3 [C20: from pyro- + gall(ic)2+-ol1] ...
12.Newton employs it in combination with pyrogallol and soda in the development of bromo-gelatine plates. 13.Two steps lead to the formation of benzodioxoles: firstly, and most importantly the synthesis of 2,2-dimethoxy propane; secondly, the exchanging reaction of 2,2-dimethoxypropane and pyrog...
Since superoxide dismutase and catalase inhibited these reactions extensively, active oxygens such as superoxide and hydrogen peroxide were considered to be involved in the oxido-reductive reaction of human hemoglobin by pyrogallol. It was also found that the metabolism of pyrogallol to purpurogallin ...
