Sodium bisulfate, also known as acid sodium sulfate, has the chemical formula NaHSO4 and is an inorganic compound. Sodium bisulfate appears as white monoclinic crystals with a sour taste. It is soluble in water but insoluble in liquid ammonia. Sodium bisulfate is hygroscopic, corrosive, highly irritating and toxic, and is widely used in analytical reagents, printing and dyeing, metal smelting, medicine, daily chemicals and other fields.

The main synthesis methods of sodium bisulfate include the chlorosulfonic acid method and the neutralization method. The chlorosulfonic acid method refers to using sodium hydroxide and chlorosulfonic acid as raw materials, adding sulfuric acid after full reaction, and finally producing sodium bisulfate. This method has the advantages of low raw material consumption and good finished product quality, but the production cost is relatively high; The neutralization method uses sodium hydroxide, water and sulfuric acid as the main raw materials and produces sodium bisulfate through direct reaction. This method has the advantages of convenient operation and low production cost, but it is easy to produce a large amount of waste acid and pollute the environment.

Sodium hydroxide is the core raw material of sodium bisulfate. Sodium hydroxide (NaOH), also known as caustic soda and caustic soda, is corrosive and highly alkaline and is widely used in the chemical industry. Sodium hydroxide is a bulk chemical. According to data released by the National Bureau of Statistics, my country’s sodium hydroxide production will reach 39.805 million tons in 2022, a year-on-year increase of 1.4%. In recent years, due to factors such as stricter environmental protection policies and equipment failures, my country’s sodium hydroxide production capacity and output growth have slowed down, but it can still meet the production demand for sodium bisulfate.

According to the “2023-2028 China Sodium Hydrogen Sulfate (Sodium Acid Sulfate) Industry Market In-depth Research and Development Prospects Forecast Report》 shows that sodium bisulfate is widely used in analytical reagents, printing and dyeing, metal smelting, medicine, daily chemicals and other fields. Driven by downstream demand, the development speed of my country’s sodium bisulfate industry continues to accelerate. At present, my country has become the world’s largest consumer of sodium bisulfate, accounting for nearly 50% of the market. In the future, with in-depth research, the application scope of sodium bisulfate will be further expanded, and its market size will continue to grow.
                              
​​ ​​The major global manufacturers of sodium bisulfate include Germany’s GRILLO-WERKE, Germany’s Merck, and Japan’s Sumitomo Chemical Co., Ltd. (SUMITOMO CHEMICAL). In terms of the local market, there are many players in my country’s sodium bisulfate market, including Jitang Co., Ltd., Yihua Chemical, Zhongcheng Chemical, Kailong Chemical, Blue Star Chemical, etc. In the future, with technological advancement, the concentration of my country’s sodium bisulfate industry is expected to further increase.

Industry analysts said that sodium bisulfate has a wide range of applications and the industry has good development prospects. Benefiting from the growth in downstream demand, my country’s sodium bisulfate production capacity has further expanded and output has continued to grow. After years of development, my country has become the world’s largest consumer of sodium bisulfate. It is expected that in the future, with the improvement of industry prosperity, the number of participants in my country’s sodium bisulfate market will continue to grow, and its market competition will become increasingly fierce.
