The development prospects of p-toluenesulfonic acid (TsOH) industry are good, Xintiandi is the largest manufacturer in my country

       P-Toluenesulfonic acid (TsOH), also known as p-toluenesulfonic acid, has a chemical formula of C7H8O3S and is an organic compound. p-Toluenesulfonic acid appears as white crystalline powder, soluble in water, alcohol, ether and other polar solvents, and slightly soluble in hot benzene. p-Toluenesulfonic acid has the characteristics of good chemical stability, easy deliquescence, and low toxicity. It is widely used in the fields of pesticides, medicine, electrochemistry, and organic synthesis.

The preparation methods of p-toluenesulfonic acid include direct sulfonation of toluene, toluene oxidation, toluenesulfonyl chloride hydrolysis, styrene oxidation, etc. The direct sulfonation method of toluene is the mainstream preparation method of p-toluenesulfonic acid in my country. This method uses toluene as the core raw material, adds sulfonating agents such as chlorosulfonic acid, sulfuric acid, and sulfur trioxide, and obtains the finished product through a sulfonation reaction. In recent years, with the continuous implementation of national environmental protection policies, Chinese companies have further increased research on green preparation methods of p-toluenesulfonic acid. The direct sulfonation method of toluene has many by-products and can easily cause environmental pollution, and will be replaced by emerging methods in the future. .

According to the “2023-2028 China p-toluenesulfonic acid (TsOH) industry market in-depth research and development prospect forecast report》shows that p-toluenesulfonic acid is widely used in many fields and has good industry development prospects. The pharmaceutical field has the largest demand for p-toluenesulfonic acid. It can be used as raw material for the preparation of doxycycline, anti-tumor drugs, cephalosporin antibiotics and penicillin antibiotics, cefadroxil, amoxicillin, and sorafenib. etc. as its end products. my country is a country with a large population, the number of cancer patients continues to grow, and the market demand for anti-tumor drugs is increasingly strong. Against this background, my country’s p-toluenesulfonic acid production continues to grow, reaching nearly 40,000 tons in 2022, setting a record high.

In recent years, with the continuous improvement of my country’s scientific research strength, p-toluenesulfonic acid has gradually been widely used in electrochemical experimental research. In March 2023, the team of Academician Hao Yue of Xi’an University of Electronic Science and Technology introduced toluenesulfonic acid into the carbon nanotube/silicon heterojunction and used its optical anti-reflection effect to increase the photovoltage of solar cells. In the future, this technology will be used in heterogeneous During the preparation of mass junction solar cells. In the future, as research continues to deepen, the application scope of p-toluenesulfonic acid will be further expanded.

my country’s p-toluenesulfonic acid industry has a high degree of concentration, with major production companies including Xintiandi, Dongguangguang, Satellite Chemical and Jinneng Technology. Xintiandi is my country’s largest producer of p-toluenesulfonic acid, accounting for nearly 25% of the market. Its annual output of p-toluenesulfonic acid reaches nearly 10,000 tons.

Industry analysts said that p-toluenesulfonic acid, as an organic acid, has broad application prospects in the fields of medicine and electrochemistry. In the future, with in-depth research and technological advancement, my country’s p-toluenesulfonic acid market space will be further expanded. In terms of market competition, my country’s p-toluenesulfonic acid industry is highly concentrated, and Xintiandi, as the leading company, occupies a major share of the market.
