Bechamp reduction

Being a precursor to many industrial chemicals, its main use is in the manufacture of precursors to polyurethane.

It is found naturally in gastric acid.The reaction was first used.General References, bechamp,.Subsequently, the reaction mixture is refluxed for 1 hour until the iron powder is mostly dissolved.3.30 g (20.0 mmol) of 4Nitroacetophenone and.19 g (75.0 mmol) of iron powder are added.Although occasionally used as a flavoring or perfume.2, the Bechamp reaction is of interest as a route to iron oxide pigments.Gently swing the separating funnel in upright position so that the solid iron hydroxide settles out.The organic layer is transferred into a 250 mL round bottom flask which had been weighed.It is a water-insoluble pale yellow oil with an almond-like odor."Alternative synthesis of the anti-baldness compound RU58841".

Subsequently, the drying agent is sucked off.

Stirring is commenced and the solution is neutralized with diluted sodium hydroxide solution (c 2 mol/L) (formation of iron hydroxide sludge!).
This reaction was originally used to produce large amounts of aniline for industry, but catalytic hydrogenation is the preferred method.
