The demand for industrial naphthalene will still rise. Japan is my country’s main import region for industrial naphthalene.

Naphthalene, also known as acene, has a molecular formula of C10H8 and a molecular weight of 128.17. It is a colorless and shiny flaky crystal. Naphthalene is insoluble in water, easily sublimates, can evaporate with water vapor, and has a special smell. It is the most important condensed ring aromatic hydrocarbon in industry. According to its different purity, naphthalene can be divided into industrial naphthalene and refined naphthalene. The purity of industrial naphthalene is generally about 96%. After further purification of industrial naphthalene to remove impurities and desulfurization, high-purity refined naphthalene can be obtained.

There are two production methods for industrial naphthalene: tar naphthalene and petroleum naphthalene. At this stage, the technical level of domestic tar naphthalene production is not much different from that of foreign countries. However, the technical level of petroleum naphthalene production is low. The industry has problems such as small scale, simple production process, and low product purity. Therefore, domestic industrial naphthalene is mainly produced from coal tar.

Industrial naphthalene is an important basic chemical raw material, which can be used to produce chemical products such as water reducing agent, refined naphthalene, phthalic anhydride, naphthol, naphthylamine, etc., and then used to produce synthetic fibers, plasticizers, rubber antioxidants, dye intermediates, and pesticides. and important raw materials for medicine, etc.

In recent years, with the development of phthalic anhydride, water reducing agent and other industries, China’s industrial naphthalene market demand has continued to rise. According to the “2022-2027 China Industrial Naphthalene Industry Market In-depth Research and Development Prospects Forecast Report released by the Industrial Research Center, in 2021 In 2018, China’s industrial naphthalene market demand reached about 1.2 million tons. However, due to the high market price of domestically supplied naphthalene, China’s industrial naphthalene import volume is much higher than its export volume. With the continuous expansion of domestic naphthalene-based phthalic anhydride production capacity, the market demand for industrial naphthalene has gradually expanded, resulting in an overall downward trend in China’s industrial naphthalene export volume. .

At present, there are a large number of enterprises in my country’s industrial naphthalene industry. In recent years, with the tightening of environmental protection supervision and the deepening of supply-side structural reform in the industry, small-scale and polluting enterprises in the industrial naphthalene industry have gradually withdrawn from the market. At this stage, China Representative companies in the industrial naphthalene industry include Shanghai Jinhuan Petroleum Naphthalene Development Co., Ltd., PetroChina Liaoyang Petrochemical Fiber Company, China Petroleum Jilin Chemical Group Company, Jiangsu Hualun Chemical Co., Ltd., Shanxi Jinyuan Coal Chemical Co., Ltd., Henan Bohai Chemical, Shanxi Wenshui Mingtai et al.

Industrial researchers said that industrial naphthalene is an important product in the deep processing of coal tar and is mainly used to produce phthalic anhydride, water reducing agent, Refined naphthalene, 2-phenol and other products. In the future, with the development of the industrial naphthalene downstream industry, China’s industrial naphthalene market demand may continue to grow. However, due to factors such as high domestic industrial naphthalene prices, China’s industrial naphthalene may still be mainly imported, and the main source of imports is Japan.
