2-Vinylnaphthalene, also known as 2-naphthaleneethylene, is a chemical substance with the chemical formula C12H10. It appears as a white to slightly light gray crystalline powder. It is insoluble in water and soluble in organic solvents such as ethanol, acetone, and benzene. At present, 2-vinylnaphthalene can be prepared from 2-naphthylethanone through sodium borohydride reduction, acid quenching, extraction, recrystallization and other steps to generate 2-naphthyl ethanol, and then dehydration of 2-naphthyl ethanol.
According to the“China 2-vinylnaphthalene Industry Market Monitoring and Future Development Prospects Research Report 2023-2027” released by the Industrial Research Center It shows that 2-vinylnaphthalene is an important type of medicine, material intermediates and optical element coating materials, and can be widely used in medicine, chemical industry, coatings and other fields. Among them, chemical industry is the main application field of 2-vinylnaphthalene. 2-vinylnaphthalene contains active vinyl groups and can be used to synthesize various polymers.

2-Vinylnaphthalene can give high molecular polymers high heat resistance, high refractive index, low dielectric loss, low dielectric constant, flame retardancy, low hygroscopicity and other characteristics. It has become one of the important raw materials for the production of high-end photoresists. 1. It plays a role in the production scenarios of I-line photoresist (365nm), G-line photoresist (436nm), KrF photoresist (248nm), ArF photoresist (193nm), and EUV photoresist (13.5nm). Important role, especially in the KrF photoresist (248nm) production scenario.

Photoresist is a photosensitive material. It refers to a corrosion-resistant thin film material whose solubility changes under the irradiation or radiation of ultraviolet light, electron beam, particle beam, etc. It is one of the key materials in the photolithography process in microelectronics manufacturing. In recent years, driven by the rapid development of the downstream market, the structure of photoresist products has been continuously optimized and upgraded, and the market penetration rate of high-end photoresists has increased significantly, which in turn has driven the continued growth of demand for 2-vinylnaphthalene. Take KrF photoresist as an example. KrF photoresist is mostly used in the 8-inch wafer manufacturing process. Its domestic market size will exceed 1.5 billion yuan in 2022. It can be seen that my country’s 2-vinylnaphthalene has a broad demand space and huge market development potential.
From the production side, the key production technology of 2-vinylnaphthalene for photoresist is still controlled by Japanese companies. The degree of localization in the domestic market is still relatively low. In the future, local companies still need to accelerate the development of key technologies. Most domestic 2-vinylnaphthalene companies mainly produce 2-vinylnaphthalene products for pharmaceutical and industrial purposes. The number of companies with the mass production capacity of 2-vinylnaphthalene for photoresists is still relatively small. Only Xi’an Qi A few companies, such as Yue Biotechnology and Changqing Evergreen Technology, need to continuously improve their domestic 2-vinylnaphthalene production capacity in the future.
Industry analysts said that 2-vinylnaphthalene is a type of fine chemical product that is used in photoresist It plays an important role in the production field and is an important raw material required for the production of high-end photoresists such as I-line, G-line, KrF, ArF, and EUV photoresists. In recent years, against the background of the gradual upgrading of domestic photoresist product structure, the demand for 2-vinylnaphthalene has been increasing, and the industry has shown great development potential. However, my country’s current production capacity of 2-vinylnaphthalene for photoresists is still relatively low. In the future, local companies will need to increase their efforts to conquer key technologies.
