Baudisch reaction
Encyclopedia
The Baudisch Reaction was discovered by Oskar Baudisch
in 1939 and further developed by his colleague Cronheim. In the reaction a solution containing aqueous hydroxylamine hydrochloride and hydrogen peroxide
reacts with benzene
or phenol
, with the assistance of copper(II) to give o-nitrosophenols. These nitrosophenols can then be used in the manufacture of dye

Hydrogen peroxide
Hydrogen peroxide is the simplest peroxide and an oxidizer. Hydrogen peroxide is a clear liquid, slightly more viscous than water. In dilute solution, it appears colorless. With its oxidizing properties, hydrogen peroxide is often used as a bleach or cleaning agent...

Phenol
Phenol, also known as carbolic acid, phenic acid, is an organic compound with the chemical formula C6H5OH. It is a white crystalline solid. The molecule consists of a phenyl , bonded to a hydroxyl group. It is produced on a large scale as a precursor to many materials and useful compounds...

Dye
A dye is a colored substance that has an affinity to the substrate to which it is being applied. The dye is generally applied in an aqueous solution, and requires a mordant to improve the fastness of the dye on the fiber....
