Demand for tetralin continues to grow, with cemented carbide being the largest application area

Tetralin is also known as tetralin and tetralin, with a molecular formula of C10H12 and a molecular weight of 132.20. Tetrahydronaphthalene is an alicyclic aromatic hydrocarbon with the smell of naphthalene and appears as a colorless liquid or transparent liquid. It is an important derivative of naphthalene. It can evaporate with water vapor and can be mixed with ethanol, butanol, ether, and acetone. A mixture of benzene, chloroform, decalin and petroleum ether, soluble in methanol and easily soluble in aromatic solvents, it is an ideal high boiling point solvent.

Tetralin is widely used in cemented carbide, medicine, papermaking, coatings and other fields. Among them, in the field of cemented carbide production, tetralin has excellent application performance as a molding agent, making tetralin the most important in the cemented carbide field. application fields. In the field of coatings, tetralin is used as a solvent, but due to its relatively high price, the application scale is small. In addition, although tetralin also has certain applications in medicine, papermaking, etc., the application scale is small and scattered. According to the “2022-2027 Tetralin Industry Market In-depth Research and Investment Prospect Forecast Analysis Report released by the Industrial Research Center, China’s demand for tetralin in 2021 will be close to 400 tons.

Industry analysts said that in recent years, with the deepening of the supply-side structural reform of the domestic economy, cutting tools, mining tools and durable The downstream demand for cemented carbide, especially mid-to-high-end cemented carbide, such as grinding tools, is growing. As a cemented carbide forming agent, the application of tetralin in the cemented carbide field is gradually increasing.

At present, there are few domestic tetralin industry manufacturers. Among them, the enterprises with larger production capacity mainly include Jiangsu Zhongneng Chemical Co., Ltd., Huangshan Bashui Chemical Additives Co., Ltd., etc. In addition, tetralin products of foreign companies represented by Evonik and DEZA are also sold in China, but their prices are high, their competitive advantages are not obvious, and they occupy a small market share. In recent years, with the extension of the industrial chain of the domestic coal chemical deep processing industry and the development of related industries, some coal chemical and crude benzene hydrogenation production companies have entered the tetralin industry, resulting in an increase in the number of companies in the tetralin industry and intensified overall competition in the industry. .
