The catalytic mixture can be used for the catalytic transformation of compounds, such as the hydrogenation of olefins, or the hydrogenation of nitro compounds.
The method comprises reacting nitro compounds containing color-forming impurities with nitric acid, neutralizing and washing the product, and distilling therefrom purified nitro compounds.
A method for stabilizing nitro compounds against discoloration.
The invention also relates to a method for producing the inventive Raney nickel catalyst and to its use in the hydrogenation of organic compounds, especially aromatic nitro compounds.
The oxidizing agent is preferably selected among aromatic nitro compounds, for example, 2-nitrobenzoic acid.
The target molecules may be nitro-containing compounds, such as nitroaromatic compounds, or lactones.
The invention relates to a process for hydrogenating halogen-substituted nitro-aromatic compounds or functional nitro-aromatic compounds using nitrogendoped carbon nanotubes (NCNTs).
Said catalyst is particularly used for hydrogenating nitro-aromatic compounds.
The nitro-hydroxy-aromatic compounds may include nitro-phenol salts or nitro-cresol salts.
Disclosed are functionalized fluoroether-functionalized nitroaromatic compounds and derivatives thereof.
