The Tobaic acid market is highly concentrated and the industrial structure will continue to be optimized.

The chemical name of Tobaic acid is 2-amino-1-naphthalenesulfonic acid, which is an important chemical raw material. Pure Tobaic acid is a white nail-shaped crystal that easily turns pink to dark red in the air. Tobaic acid is easily soluble in liquid alkali, soluble in hot water, slightly soluble in cold water, ethanol, ether, etc., and is toxic.

Tobaic acid has a wide range of applications, mainly in the fields of organic synthesis, dyes, and medicine. As an important dye intermediate, Tobaic acid can be used to prepare dye products such as J acid, scarlet acid, gamma acid, fluorescent whitening agent, organic magenta, and Lithosol magenta. my country is a major producer and consumer of tonic acid. While its production capacity meets domestic market demand, it is also exported to overseas markets such as India, South Korea, Japan and Southeast Asia.

According to the “2022-2026 China Tocolic Acid Industry Market Monitoring and Future Development Prospects Research Report released by the Industrial Research Center , Domestic Tobaic acid production companies include Inner Mongolia Xinya Chemical, Tangshan Huayi Industrial, Gansu Yonghong Dyeing, Tianjin Kede Chemical, Tai’an Jiangzhou Biology, etc. my country’s tonic acid market is highly concentrated, with Inner Mongolia Xinya Chemical accounting for nearly 60% of the domestic market and about 50% of the international market. The sulfonated tonic acid produced by the company has been designated as a national standard product.

Sulfonated tobaic acid and refined tobaic acid are upgraded dye intermediates that extend the industrial chain on the basis of tobaic acid. Refined Tobaic acid is mainly produced from Tobaic acid wastewater, involving processes such as freezing crystallization, filtrate concentration, high-temperature cooling, low-temperature crystallization, filtration, ammoniation, and acid precipitation. With the advancement of domestic technology, the purity of my country’s refined tonic acid has been greatly improved, with the purity of some products reaching more than 99%. In recent years, in order to increase the added value of tocolic acid products and expand production efficiency, there have been an increase in sulfonated tocolic acid-related construction projects. As environmental protection supervision becomes increasingly strict, the structure of the tobutyl acid industry will continue to be optimized in the future.

The raw materials for the production of Toa’s acid include 2-naphthol, o-nitroethylbenzene solvent, chlorosulfonic acid, soda ash, ammonium bisulfite, hydrochloric acid, etc. The raw materials for the production of Toa’s acid are mostly corrosive and toxic, and will occur during the production process. Discharging a large amount of wastewater can easily cause environmental pollution. In recent years, in order to promote the green and safe development of tonic acid production, domestic and foreign companies have made a series of explorations, such as reducing the dosage of 2-naphthol, improving the production process, using activated carbon/wastewater treatment equipment to treat 2-naphthol, etc. .

Industry analysts said that my country is a major dye production country, and as an important dye intermediate, tonic acid has a huge market demand. my country is a major producer and consumer of tocolic acid, but the production of tococonic acid can easily cause environmental pollution. In the future, as environmental protection supervision becomes increasingly strict and market competition intensifies, the tococonic acid industrial structure will continue to be optimized, and the industry will develop toward high value-added and environmental protection. , upgrade in the direction of high-end and refinement.
