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.
- p-Nitrobenzoic acid can be used as a chemical reagent to test alkaloids and calibrate standard alkali solutions.
- p-Nitrobenzoic acid is used to prepare the anesthetic procaine hydrochloride and dye intermediates, and can also be used to prepare light filters. It can also be used in the production of photosensitive materials, the production of photosensitive materials, and the electropaste liquid in capacitors.
- p-Nitrobenzoic acid is an intermediate in organic synthesis of medicines, dyes, veterinary drugs, photosensitive materials, etc. Used to produce procaine hydrochloride, procainamide hydrochloride, p-aminomethylbenzoic acid, folic acid, benzocaine, antitussive, cephalosporin V, p-aminobenzoylglutamic acid, benzoic acid Neil, and produces reactive brilliant red M-8B, reactive red violet X-2R, as well as filters, color film couplers, metal surface rust removers, sunscreens, etc.
