Description
Technical Field

[0002] p-Nitroaniline is an important organic synthesis intermediate with wide applications in dyes, pharmaceuticals, and pesticides. Early preparation methods primarily employed the traditional nitration-reduction process, using aniline as a raw material, nitrifying it with mixed acids, and then reducing it. This method required harsh reaction conditions, easily generating large amounts of waste acid and residue, polluting the environment, and exhibiting low atom utilization. With the rise of green chemistry, new methods have emerged, such as using environmentally friendly nitrating agents or catalysts to improve reaction selectivity and yield while reducing pollution. However, current methods still suffer from high costs and complex processes, necessitating the development of more efficient, environmentally friendly, and economical preparation processes to meet growing market demand and align with sustainable development principles.
[0003] The production of p-nitroaniline requires feeding, and the traditional feeding method relies on manual operation based on experience. This is not only inefficient and lacks precision, but also prone to introducing impurities due to improper operation, affecting the product quality and production efficiency of p-nitroaniline. The feeding process of p-nitroaniline is time-consuming and labor-intensive, which brings inconvenience to the production of p-nitroaniline and increases the production time. Utility Model Content
