-
Paragraph 0013, (2018/11/03)
The invention discloses a synthesis method of p-nitrobenzoic acid. Reacting is performed by adopting 2-p-nitrobenzoyl-2-acetamino-1,3-propylene glycol and nitric acid as raw materials and water as a solvent; after the reacting, p-nitrobenzoic acid is obtained through crystallization. According to the method disclosed by the invention, the reaction conditions are mild, the reacting is performed atrelatively low temperature and under normal pressure, the requirements on equipment are low, the reaction line is short and thus the reacting is easy to control and safe and reliable; moreover, the obtained crude product has the advantages of easiness in separation, high yield and high purity and is suitable for popularization.
