The application fields of sodium p-aminobenzene sulfonate continue to expand, with aniline as the main raw material

Sodium p-aminobenzene sulfonate is an organic compound. Under normal conditions, the pure product mainly appears as shiny white crystals. Sodium p-aminobenzene sulfonate is mainly used to synthesize sulfonamide drugs, dyes, fluorescent whitening agents, etc. It can also be used to synthesize spices, pesticides, etc. At present, 97% sodium p-aminobenzene sulfonate is mainly used in industry. Under normal conditions, it mainly appears as light pink or rose-colored crystals.

The main raw material for the production of sodium p-aminobenzene sulfonate is aniline. my country is a major producer and exporter of aniline. According to data from the General Administration of Customs of China, my country exported 28,732 tons of aniline in 2022, with sales reaching 2.6 billion yuan. Sufficient production of aniline has laid a raw material foundation for the production of sodium p-sulfaniline.

The production process of sodium p-aminobenzene sulfonate is mainly chemical synthesis. This method mainly uses aniline to carry out translocation, sulfonation, neutralization, filtration, cooling and crystallization and other processes to prepare sodium p-aminobenzene sulfonate. It has the advantages of mild reaction conditions, high yield, and stable product quality. However, the aniline synthesis method easily produces a large amount of waste gas and waste liquid, which causes serious environmental pollution and puts great environmental pressure on enterprises. Some companies are exploring new production processes, such as using catalysts and other means to reduce waste water and exhaust emissions. It is expected that new, greener and more environmentally friendly processes will become the main direction for innovation in the production process of sodium p-aminobenzene sulfonate in the future.

At present, sodium p-aminobenzene sulfonate is widely used in medicine, dyes, pesticides and other fields. In the field of dyes, sodium p-aminobenzene sulfonate is the main component of acid dyes, direct dyes, reactive dyes and other products. It can also be made into dye additives such as anti-dye H, melting salt B, whitening agent BG and so on. Sodium dimethoate is a commonly used pesticide, with 97% sodium p-aminobenzene sulfonate as the main component. Sodium dimethonate has low toxicity to humans and livestock. It is a highly efficient systemic fungicide and has good control effects on plant rust. The academic community is studying the role of sodium sulfanilic acid in the water circulation system. It is expected that as the research becomes more in-depth, the application fields of sodium sulfanilic acid will continue to expand, and the market will expand accordingly.

According to the “2023-2028 China Sodium Parasaminobenzene Industry Market In-depth Research and Development Prospects Forecast Report released by the Industrial Research Center 》shows that sodium p-aminobenzene sulfonate belongs to the petrochemical and chemical industry and is one of the key areas of national supervision. In recent years, the country has vigorously promoted green development in all walks of life. In 2022, it released policies such as the “Comprehensive Work Plan for Energy Conservation and Emission Reduction during the “14th Five-Year Plan””, which focused on strictly controlling the emission of pollutants in the production of petrochemical and chemical related industries and promoting the petrochemical and chemical industry. Industrial greening process.

Industry analysts said that due to the impact of policies, my country’s sodium parasilicate industry will adjust its production structure, optimize production processes, and save money. Produce energy and reduce pollutant emissions. my country’s sodium parasilicate companies should strengthen technological innovation, improve production processes, improve product quality and production efficiency, and at the same time strengthen ties with upstream and downstream enterprises to develop collaboratively, extend the sodium parasilicate industry chain, and increase product added value.
