How do you make aniline Tribromoaniline?
A solution is prepared by adding 8.4 ml of bromine in 20 ml glacial acetic acid. Another second solution is prepared adding 5 ml of aniline in 20 ml of glacial acetic acid in a conical flask. The first solution is added drop wise to the second solution from a dropping funnel.

What is Benzoylation in chemistry?
Benzoylation is introduction of benzoyl group (C6H5CO−) by replacement of H− attached to ‘O’ or ‘N’ or to aromatic nucleus.

What type of reaction is benzoylation?
It is a base-catalyzed reaction. The base is necessary to encourage an equilibrium shift towards the formation of amides. The base also neutralizes the hydrochloric acid which is formed in the process, thereby preventing the further protonation of the amide product formed.
Why is benzoylation preferred over acetylation?
There are, in fact, two major advantages of benzoylation over acetylation, namely : (a) First, generally the benzoyl derivatives are obtained as crystalline solids having comparatively higher melting points than the corresponding acetyl derivatives , besides, possessing lower solubilities in a wide range of solvents.
Can 2-tribromoaniline be oxidized in aqueous sulphuric acid?
Electrochemical oxidation of 2,4,6-tribromoaniline in aqueous sulphuric acid solutions at platinum electrode has been studied by rotating disc electrode and cyclic voltammetry. 2,4,6-Tribromoaniline on closed-tube pyrolysis yields polybromophenazines. It is an intermediate in the formulation of flame retardants incorporated to plastic materials.
What is the yield of 2 4 6 tribromoaniline?
The separated product is filtered, washed with water and recrystallised from rectified spirit. The yield is about 10 g (55.6%). The synthesized 2,4,6-tribromoaniline was obtained as colourless crystals, % yield: 58.46 and of m.p. 120°.
How is tribromoaniline made?
When the water in C becomes almost colourless (about 40 minutes), due to evaporation of bromine, the current of air is stopped, and tribromoaniline is filtered at pump, washed well with water and drained. The product is recrystallised from rectified spirit, using animal charcoal.
What is the role of bromine in tribroboaniline?
Here presence of bromine atoms in tribroboaniline, reduces the basic properties of the amino group, and salts even with strong acids are almost completely hydrolysed in presence of water. Aim: To prepare 2, 4, 6-tribromoaniline from aniline.
