2-Methylnaphthalene has broad application prospects and my country has become the world’s largest producer

2-Methylnaphthalene, also known as β-methylnaphthalene, is an organic compound with the chemical formula C11H10. It appears as a white to light yellow crystalline powder. It is insoluble in water and soluble in most organic solvents such as ethanol, ether, and benzene. . 2-Methylnaphthalene is an important fine chemical raw material and is widely used in chemical industry, rubber, plastics, agriculture, medicine, construction, textile and other fields.

Specifically, in the construction field, 2-methylnaphthalene can be used in the production of concrete water-reducing agents; in the medical field, 2-methylnaphthalene can be used in the production of vitamin K3 and oral contraceptives; in the agricultural field, 2-methylnaphthalene 2-Methylnaphthalene can be used in the synthesis of plant growth regulators and feed additives; in the chemical industry, 2-methylnaphthalene can be used as an intermediate in the synthesis of chemical products such as surfactants and lubricants, and can also be used as a raw material for polynaphthalene 2 Production scenarios of ethylene glycol formate (PEN) and liquid crystal polymer (LCP) monomers 2,6-naphthalenedicarboxylic acid and 2,6-naphthalenedicarboxylic acid dimethyl ester.

2-Methylnaphthalene comes from coal tar wash oil fractions, petroleum processing by-product tar, heavy aromatic hydrocarbons, etc. Its production technology route is mainly obtained by separation and purification from coal tar wash oil fractions. However, due to the complex composition of the coal tar wash oil fraction, it is difficult to separate and purify 2-methylnaphthalene through a single separation method. Instead, multiple methods such as recrystallization, azeotropic distillation, acid-base washing, and solvent extraction are required. It is made by a combination of methods, and there are many technological processes. In the future, relevant processes need to be continuously improved and perfected.

As a major coal producer, my country has relatively high coal tar output, which has laid a good foundation for the development of the 2-methylnaphthalene industry. According to the “China 2-methylnaphthalene Market Monitoring and Future Development Prospects Research Report 2023-2027” released by the Industrial Research Center It shows that my country’s coal tar production has exceeded 27 million tons in 2022. Against this background, domestic 2-methylnaphthalene production in 2022 will be approximately 1,200 tons.

Industry analysts said that my country’s main 2-methylnaphthalene production companies include Shanghai Jinhuan Petroleum Naphthalene, Qujing Zhongyi Fine Chemical, Panjin Shengtian Chemical, Liaoning Donghao Chemical, Jiaocheng County Huihuang Chemical, Hebei Sinochem Xinbao Chemical Technology, Pengchen New Material Technology, Sinochem International New Materials, Shandong Hantai Petrochemical, Beijing Zhou There are many companies including Yuan Chemical, Laiwu Parkson Chemical, and Hebei Sinochem Fuding Chemical Technology. With the gradual release of production capacity of local enterprises, my country has become the largest producer of 2-methylnaphthalene in the world. In 2022, domestic production capacity will account for more than 50% of the global total production capacity, and the industry development trend is improving.
