A method for the oxidation of nitrogen substance to nitrogen dioxideJUN ALFRED J HALEYANDERSEN HOLGER C
A lead dioxide tube for oxidation of nitric oxide was prepared by anodic oxidation of a lead electrode of 30 mm i.d. and 300 mm in length. Electrolysis was carried out in 5% sulufuric acid with a platinum wire as a cathod by a current density of 10 mA/cm for 30 h, and the deposi...
Petroleum sulfides (obtained as concentrates from appropriate distillates) were oxidized with a mixture of air and nitrogen dioxide to sulfoxides, with yields of 75-80% for sulfoxide sulfur, but the process was complicated by secondary processes: the formation of up to 30% of nitrosulfoxides of...
OXIDATION NUMBERS The oxidation number or state refers to the charge an atom would have if the pairs of electrons in each bond of the compound belonged to the atom with the most electronegative charge, as if the electrons had been transferred and not shared. For ionic compounds this is alread...
A comparison was made of the different technological treatments for the preparation of colorless sunflower protein products from the viewpoint of the effect of processing conditions on the extraction yield of nitrogen and lipid, chemical... HM Bau,DJ Mohtadi-Nia,L Mejean,... - 《Journal of th...
The increase in catalyst concentration increased the number of reactive sites and enhanced the light absorption for photocatalysis [151]. The higher concentrations of the catalyst may result in light-scattering and screening effects due to high opacity caused by an excess catalyst which compromised ...
In addition, the number of reports on unaccounted high nitrogen losses in wastewater treatment is gradually increasing, indicating that anaerobic ammonium oxidation may be more widespread than previously assumed. The recently developed nitrification systems in which oxidation of nitrite to nitrate is ...
A number of enantiopure N-sulfonyloxaziridines, most derived from camphor, have been used for this purpose as shown in Scheme 4. Of these reagents, the (−)-N-(phenylsulfonyl)(3,3-dichlorocamphoryl)oxaziridine 145 generally gives the highest ee’s. Representative examples of asymmetric ...
Dilution of the burning mixture with aninertgas, such asheliumornitrogen, lowers the temperature and, consequently, thereaction rate. Great amounts ofinert gasextinguish theflame, and the same result is achieved when substances that remove any of the active species are added to the flame. Condit...
(Methods). Thus, our approach describes the spatial patterns of oxidative weathering rate as a function of topographic slope and rock type, which leads to simulations that are consistent with an assessment of global rock nitrogen weathering patterns which are dominated by denudation of fine-grained ...
