Ph of nitrobenzene
WebTwo Pd/γ-Al2O3 catalysts are examined for the vapor phase hydrogenation of nitrobenzene over the temperature range of 60–200 °C. A 1 wt % catalyst is selected as a reference material that is diluted with γ-alumina to produce a 0.3 wt % sample, which is representative of a metal loading linked to a candidate industrial specification aniline synthesis catalyst. WebMay 1, 2013 · Nitrobenzene kinetic reduction experiment was performed with 48 mM organic buffer (pH 6.0 and 7.0) containing various combinations of nitrobenzene (130 μM or 1680 μM), Fe (II) (4.4–4.6 mM) and iron oxide (magnetite, goethite or hematite; 20 m 2 L −1 BET surface areas).
