Basic Info

What is p-Nitrobenzoic acid?

4-Nitrobenzoic acid, also known as p-nitrobenzoic acid, is an organic compound with the chemical formula C6H4(NO2)CO2H. It belongs to carboxylic acid, which is a compound in which the para-position (4-position) of benzoic acid is substituted by a nitro group. It is a type of nitrobenzoic acid and is an isomer of o-nitrobenzoic acid and m-nitrobenzoic acid.

p-Nitrobenzoic acid is a pale yellow and odorless crystal. It is acidic because of its carboxyl group. The reason why it is more acidic than benzoic acid is that there is a nitro group on the benzene ring, and the nitro group is an electron withdrawing group, which can make the carboxyl group of p-nitrobenzoic acid more acidic through the conjugation effect.

It is gotten by the oxidation of p-nitrotoluene. The oxidant can utilize salt dichromate, air, manganese ore powder, nitric acid and so on. Using p-nitrotoluene as a raw material, in the presence of sulfuric acid, the oxidation response is accomplished with salt dichromate at 55 ° C to produce p-nitrobenzoic acid. The reaction service is filtered system, centrifugally dehydrated, washed with water and also dried to acquire the finished product. Additionally, making use of the dextrorotate 1-p-nitrophenyl- 2-amino-1,3-propanediol in the production of chloramphenicol, it is very easy to oxidize p-nitrobenzoic acid with nitric acid.

p-Nitrobenzoic acid Uses

  • 4-Nitrobenzoic acid is used in the synthesis of anti-Trypanosoma cruzi drugs for the treatment of Chagas disease.
