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
- Organic Synthesis
4-Nitrobenzoic acid is an intermediate in organic synthesis of medications, dyes, vet medicines, as well as photosensitive products. For the production of procaine hydrochloride, procainamide hydrochloride, p-aminomethyl benzoic acid, folic acid, benzocaine, coughing, cephalosporin V, p-aminobenzoyl glutamic acid, benzyl Neil, as well as the manufacturing of reactive great red M-8B, responsive red violet X-2R and also filters, shade movie couplers, metal surface area rust cleaners, sun blocks, etc - Other
p-Nitrobenzoic acid can be made use of in the production of photosensitive materials and the electrical paste of capacitors. At the same time, the basic service of 4-nitrobenzoic acid can figure out alkaloids.
