Question

Как из хлорбензола получить 2,4,6 - тринитрофенол?

Answer 1

Ответ:

С6H6Cl+NaOH= C6H5OH+NaCl

C6H5OH+3Br2=3HBr+2,4,6 трибромфенол;

С6H5OH+2YNo3 конц=H2O+2,4,6тринитрофенол или пикриновая кислота  

Вроде бы так если не ошибаюсь

How to Obtain 2,4,6-Trinitrophenol from Chlorobenzene?

To obtain 2,4,6-trinitrophenol (also known as picric acid) from chlorobenzene, several steps need to be followed. Here is a detailed procedure:

1. Nitration of Chlorobenzene: The first step is to nitrate chlorobenzene by introducing nitro groups (-NO2) onto the benzene ring. This can be achieved by treating chlorobenzene with a mixture of concentrated nitric acid (HNO3) and concentrated sulfuric acid (H2SO4). The reaction is carried out under controlled conditions, such as low temperature and slow addition of the reagents, to prevent excessive nitration. The product of this step is 2,4,6-trinitrochlorobenzene.

2. Hydrolysis: The 2,4,6-trinitrochlorobenzene obtained from the previous step is then hydrolyzed to convert the chlorine atom (-Cl) into a hydroxyl group (-OH). This can be achieved by treating the trinitrochlorobenzene with a strong base, such as sodium hydroxide (NaOH), in a suitable solvent. The reaction results in the formation of 2,4,6-trinitrophenol.

It is important to note that the process described above is a simplified overview of the steps involved in obtaining 2,4,6-trinitrophenol from chlorobenzene. The actual procedure may involve additional purification and isolation steps to obtain a pure product.
