Tetrabutyltin is an organic compound with the chemical formula C16H36Sn. It appears as a colorless liquid, insoluble in water, and soluble in most organic solvents. There are various methods for producing tetrabutyltin, mainly including Grignard method, alkyl aluminum method, Wu method, direct method, etc. Among them, the commonly used method for industrial production of tetrabutyltin is the Grignard method, which refers to the method of using tin tetrachloride as raw material and generating tetrabutyltin through chemical reaction.

According to the "2023-2027 China Tetrabutyltin Industry Market Monitoring and Future Development Prospects Research Report" released by the Xinshijie Industry Research Center, tetrabutyltin is an important organic chemical intermediate, and its downstream products include organic tin heat stabilizers, synthetic plasticizers, organic tin catalysts, gasoline explosion-proof agents, ink additives, pesticides, broad-spectrum disinfectants, etc. The terminal application fields involve pesticides, chemicals, petroleum, plastics, medicines, etc.

Among them, heat stabilizer is the main downstream product of tetrabutyltin. Tetrabutyltin has the advantages of good stability, strong weather resistance, high transparency, etc., and has good compatibility with PVC (polyvinyl chloride). Therefore, tetrabutyltin is mainly used as a stabilizer in PVC product production scenarios, such as PVC pipes, PVC hard sheets, etc.

PVC is one of the five general resins. It has been widely used in pipes and fittings, shoes, profile doors and windows, building materials, cable materials and other fields. In 2022, the domestic PVC market size is about 192.58 billion yuan, a year-on-year increase of 20.8%. In recent years, driven by the rapid development of the domestic PVC market, the market demand for tetrabutyltin has continued to increase, and the output has continued to increase, and the industry has shown good development prospects. In addition to PVC heat stabilizers, tetrabutyltin also has broad development prospects in the field of antifouling coatings. When tetrabutyltin is used as a marine antifouling coating, it can reduce the membrane material of water, thereby ensuring the normal operation of the hull.

Domestic tetrabutyltin production enterprises mainly include Yunnan Tin Industry Tin Chemical Materials, Hangzhou Ruike Chemical, Jiangsu Nantong Aidewang Chemical, Shanghai Shisihewei Chemical, Jinan Lanxess New Materials, etc. Among them, Yunnan Tin Industry Tin Chemical Materials is the core supplier of tetrabutyltin in China and the only company in the world with the most complete tin chemical products. At present, the company's annual tetrabutyltin production capacity has reached 1,400 tons. In the future, as local companies accelerate the improvement of their technical level, the domestic tetrabutyltin production will continue to increase.

Industry analysts from Xinshijie said that tetrabutyltin is an important organic chemical intermediate, and its downstream applications involve pesticides, chemicals, petroleum, plastics, medicines, coatings and other fields, and the demand space is relatively broad. After continuous research and development in recent years, many companies in my country have laid out the tetrabutyltin market. At the same time, an industry-leading company, Yunnan Tin Industry Tin Chemical Materials, has also emerged. But overall, my country's tetrabutyltin production capacity is still relatively low, and local companies need to accelerate the improvement of their technical level in the future.
