Depending on the reaction conditions (the amount of NaBH4, the substituent of nitroarenes, and the sequential addition of HCl), nitroarenes were converted to corresponding azoarenes (up to 95%), aminoarenes (up to 99%), and 4,4′-diaminobiaryls (up to 99%). songjl@iccas.ac.cn, hanbx@iccas.ac.cn
For the latter, a different optimum was identified for each metal. The obtained bimetallic NiCo porous materials show superior catalytic performance towards hydrolytic dehydrogenation of ammonia borane, thereby nitrobenzene with reducible functional groups can be reduced with high selectivity to the corresponding aniline. Ru/TiO2 catalyst exhibits excellent catalytic performance for selective reduction of 4-nitroacetophenone to 4-aminoacetophenone at the normal temperature and atmospheric hydrogen. Falk Harnisch, Carla Gimkiewicz, Birthe Bogunovic, Robert Kreuzig, Uwe Schröder. By continuing you agree to the use of cookies. Journal of the Taiwan Institute of Chemical Engineers. Moreover, 99.9% selectivity to 4-aminoacetophenone can be obtained over the 2.7 wt% Ru/TiO2(anatase) catalyst even in a relatively wide temperature (55-115 °C) and time range (1-12 h). modification of samples with copper nitrate increases the number of Lewis acid sites and decreases the number of Brønsted acid sites as copper embeds into cation exchange positions. Effect of shocked nitrobenzene concentrations on the operational performance of anaerobic sequential batch reactor. (redox) Preparing steps of aniline from nitrobenzene Nitrobenzene is reduced to aniline salt by Sn / concentrated HCl.
The formation of nitroso-, azo- and azoxy-aromatics depends of a relatively complex scheme involving consecutive reactions. For reducing nitrobenzene into an ion of phenyl ammonium a mixture of conc.

A membrane-free, continuously feeding, single chamber up-flow biocatalyzed electrolysis reactor for nitrobenzene reduction. This offers thus a strong basis to better apprehend catalytic processes on the metal surface and also explore how these can be affected by the stabilizing molecules as well as the ruthenium crystallographic structure. In situ FT-IR spectroelectrochemical study of the reduction of 1,4-dinitrobenzene in room-temperature ionic liquids. The reduction of nitrobenzene is strongly influenced by the type of Me-PANI-AC electrocatalyst. This is an weak acid and strong base reaction. sulfuric acid and conc.

In this work, a bimetallic nickel-cobalt material with porous structure was developed through the pyrolysis of ZIF-67 incorporated with Ni ions. Cooperative role of electrical stimulation on microbial metabolism and selection of thermophilic communities for p-fluoronitrobenzene treatment. Hence it has to be produced by following a two-step process. The as prepared CCD was then hybridized with halloysite nanotubes (Hal) through hydrothermal treatment to furnish a nanocomposite, Hal-CCD that was subsequently applied as support to stabilize Pd nanoparticles.
