How can you prepare benzene diazonium chloride from aniline?
Benzene diazonium chloride is prepared by the reaction of aniline. Once aniline reacts with nitrous acid at low temperatures (0-50?), benzene diazonium chloride is given as the product. If the temperature is raised, benzene diazonium chloride decomposes to phenol.How do you make benzene diazonium salt from aniline?
One of the most common methods of preparation of diazonium salt is by reacting nitrous acid with aromatic amines. The reaction of aniline (aromatic amine) with nitrous acid results in the diazonium salt formation which is benzene diazonium chloride.What is the reaction of aniline to benzene diazonium chloride?
Aniline reacts with benzene diazonium chloride to form p-amino azobenzene.- The aniline undergoes reaction with nitrous acid giving benzene diazonium chloride, NaCl and water molecules. When benzene diazonium chloride undergoes reaction; Nitrogen gas is released as a byproduct which confirms the reaction.
