Step 2: Hydrolysis of 1-Bromo-4-nitrobenzene

The next step in the production process is the hydrolysis of 1-bromo-4-nitrobenzene.
This is done by treating 1-bromo-4-nitrobenzene with a solution of sodium hydroxide.
The reaction is highly exothermic, and it produces 4-amino-2-nitrotoluene, which is a yellow liquid with a strong odor.

Step 3: Chlorination of 4-Amino-2-nitrotoluene

The next step is the chlorination of 4-amino-2-nitrotoluene.
This is done by treating 4-amino-2-nitrotoluene with a solution of chlorine gas.
The reaction is highly exothermic, and it produces 4-chloro-2-nitrotoluene, which is a yellow liquid with a strong odor.

Step 4: Dehydrogenation of 4-Chloro-2-nitrotoluene

The next step is the dehydrogenation of 4-chloro-2-nitrotoluene.
This is done by treating 4-chloro-2-nitrotoluene with a hot catalyst, such as copper oxide.
The reaction is highly exothermic, and it produces 1-chloro-4-nitrobenzene, which is a colorless liquid with a strong odor.

Step 5: Bromination of 1-Chloro-4-nitrobenzene

The final step in the production process is the bromination of 1-chloro-4-nitrobenzene.
This is done by treating 1-chloro-4-nitrobenzene with a solution of hydrobromic acid in water.
The reaction is exothermic, and it produces 1-bromo-4-nitrobenzene, which is a colorless liquid with a strong odor.
