As a dye intermediate, 6-nitrate has a broad market space

​ ​ 6-Nitro, also known as 6-nitro-1,2-diazooxynaphthalene-4-sulfonic acid, is a dye intermediate. 6-nitrate appears as yellow or orange crystals, is soluble in water, and is produced by nitrification of 1,2,4-acid oxide. 6-nitrate has the advantages of good chemical stability and low acidity. As a dye intermediate, it can be used to produce complex dyes, acid dyes and mordant dyes.

6-The nitrate industry has high technical barriers, difficult production, and agglomeration is prone to occur during the production process. In recent years, Chinese enterprises and scientific research institutions have continued to increase research on 6-nitrate preparation methods and have made many new developments. Using 1,2,4 acid oxygen species as the main raw material, adding sulfuric acid for stirring, and then diluting with water, filtering, drying and other processes, the anti-caking 6-nitrate can be finally produced. In the future, with in-depth research and technological advancement, my country’s 6-nitrate production and quality are expected to further improve.

According to the “2023-2028 China 6-Nitrogen Industry Market In-depth Research and Development Prospects Forecast Report released by the Industrial Research Center , Dye intermediates can usually be divided into naphthalene series intermediates, benzene series intermediates, anthraquinone series intermediates and toluene series intermediates, etc. 6-nitrate belongs to naphthalene series dye intermediates. According to statistics from the China Dyestuff Industry Association, my country’s dye intermediate output will reach 516,000 tons in 2021, a year-on-year increase of 28.7%. The development of the dye intermediates industry is accelerating, bringing broad market space for my country’s 6-nitrate.

6-nitrate is mainly used to produce complex dyes, acid dyes and mordant dyes, with nylon fiber, silk and protein fiber as its end products. Acid dyes, also known as anionic dyes, contain acidic groups in their molecules. Acid dyes have the characteristics of fast coloring, bright color, and complete color spectrum, and are widely used in the fiber field. my country’s demand for acid dyes will reach 69,000 tons in 2022, a year-on-year increase of 5.3%. 6-nitrate can be used to produce acid dye – acid black. With the growth of downstream demand, the development space of my country’s 6-nitrate industry continues to expand.

The main manufacturers of 6-nitrate in my country include Shandong Dongao Chemical Technology Co., Ltd., Jiujiang Shanshui Technology Co., Ltd., Shandong Linyi Sanfeng Chemical Co., Ltd., Quzhou Mingfeng Chemical Co., Ltd., Hangzhou Yijiang Industrial Co., Ltd., etc. Shanshui Technology is my country’s leading 6-nitrate enterprise. At present, the company has independently developed a method to produce 6-nitrate using aqueous low-pressure continuous hydrogenation reduction technology. This method has the advantages of green environmental protection and good quality of finished products, and is expected to become a 6- Main stream preparation method of nitrate.

Industry analysts said that 6-nitrate has the advantages of good chemical stability and low acidity, and is widely used in the field of acid dyes. As market demand gradually releases, the development prospects of the industry will continue to improve. In recent years, Chinese companies have continued to increase research on 6-nitrate preparation methods. In the future, as the maturity of technology continues to improve, the development speed of my country’s 6-nitrate industry will accelerate.
