Beschreibung

Allgemeine Beschreibung

Nitrobenzene is an aromatic nitro compound. It is mainly used as a starting material to produce aniline. It is also used in the manufacture of pharmaceuticals, dyes, and polymers. Additionally, nitrobenzene is also employed as a solvent in organic synthesis, especially for electrophilic reagents.

Anwendung

Nitrobenzene can be used as a reactant to synthesize aniline by selective hydrogenation reaction using Ru/SBA-15 catalyst.
