Beschreibung

Allgemeine Beschreibung

Nitroethane reacts with sodium to afford sodium-nitroethane. Solution of nitroethane in caustic potash reacts with bromine to afford monobromnitroethane. It can undergo nitroaldol (Henry) condensation reaction with various aldehydes in the presence of copper(II) arylhydrazone complexes (catalyst).
pK of nitroethane is 8.60.4
Nitroethane is an aprotic solvent with high polarity, which on oxidation with glucose oxidase gives nitrite, acetaldehyde and hydrogen peroxide as the major products.

Anwendung

Nitroethane may be used in the synthesis of the following compounds:

• β-nitro amine derivatives
• β-aryl nitroethylenes
• 2-alkylthio-3-alkylamino-1-aryl(hetaryl)-4-nitropentene

Sonstige Hinweise

major impurity is 2-nitropropane
