Obtaining Picric Acid from Phenol
Nitration of Phenol
Picric acid is obtained from phenol by the process of nitration. In this process, phenol is first treated with a mixture of concentrated nitric acid and concentrated sulfuric acid to form 2,4,6-trinitrophenol, which is commonly known as picric acid.
Steps involved in the process of nitration of phenol:
1. Phenol is mixed with a mixture of concentrated nitric acid and concentrated sulfuric acid.
2. The mixture is heated gently to initiate the reaction.
3. Nitration takes place, and 2,4,6-trinitrophenol is formed.
4. The mixture is then cooled and diluted with water.
5. The resulting solution is then filtered to obtain solid picric acid.
Why Nitration of Phenol?
Phenol is a highly reactive compound that can undergo various chemical reactions. One of the most common reactions of phenol is nitration. Nitration of phenol is a highly exothermic reaction that results in the formation of picric acid.
Picric acid has numerous industrial applications, including its use as a dye, a chemical intermediate, and an explosive. It is also used in the manufacturing of medicines and as a laboratory reagent.
Conclusion:
Thus, picric acid can be obtained from phenol by the process of nitration. This process involves the use of concentrated nitric acid and concentrated sulfuric acid to convert phenol into picric acid. Nitration of phenol is a highly exothermic reaction that requires proper handling and safety precautions.
