The development trend of isophthaloyl chloride industry is improving as the upstream and downstream of the industrial chain continue to benefit.

Isophthaloyl chloride is an organic compound with the chemical formula C8H4Cl2O2. It appears as a colorless or light yellow crystalline powder. It is insoluble in water and easily soluble in organic solvents such as benzene, toluene, xylene, ether, and chloroform. There are many methods for producing isophthaloyl chloride at present, including phosgene method, phosphorus trichloride method, phosphorus pentachloride method, sulfoxide chloride method, dimethyl isophthalate chlorination method, isophthalic acid chloride method, etc. Formic acid chlorination method, etc.

Isophthalic acid is the main raw material of isophthaloyl chloride. Currently, with many domestic companies actively deploying in this field, its output is in a continuous growth trend. Domestic isophthalic acid companies mainly include Yanshan Petrochemical, Yuanda New Materials, Zhongshun Chemical, Kemike Chemical, Yudeshun Chemical, etc. The current output of isophthalic acid has exceeded 250,000 tons. The continued growth of raw material output in the upstream has created strong conditions for the development of the domestic isophthaloyl chloride industry.

Isophthaloyl chloride is flammable, decomposes when exposed to water and alcohol, and easily absorbs water to decompose. It is an important chemical raw material, pesticide, and pharmaceutical polymer intermediate, and has a wide range of uses. Isophthaloyl chloride can be used as a raw material for the production of aromatic fiber materials in textile, rubber, environmental protection, electronics and other fields; it can be used as a modifier of polymers in medicine, pesticides and other fields; it can be used as a power battery The raw materials for diaphragm production are used in automobiles, electric power, energy and other fields; they can be used as raw materials for polyaramid and polyarylate production and are used in dyes, environmental protection, medical, electronics, machinery and other fields. Among them, meta-aramid, one of the aromatic fiber materials, is the main downstream application market of isophthaloyl chloride.

Currently, with the increasingly abundant supply of isophthaloyl chloride raw materials and the continuous development and expansion of the application market, its industry shows good development prospects. According to the “Isophthaloyl Chloride Industry In-depth Market Research and Investment Strategy Suggestions Report 2023-2027” released by the Industrial Research Center, The domestic isophthaloyl chloride market size has reached 1.32 billion yuan in 2022, and the compound annual growth rate of its market size is expected to be close to 20% from 2023 to 2027.

At present, the companies that are developing the isophthaloyl chloride market in China mainly include Kaiben Jinwei, Yantai Yuxiang Fine Chemicals, Shandong Kaisheng New Materials, Kefeng Chemicals, Sanli Bennuo New Materials, Ruiyuan Chemicals, etc. Domestic isophthaloyl chloride companies are mostly small and medium-sized companies with low technical level and small scale. Therefore, their related products are far behind those of leading foreign companies. In the future, local companies will need to increase their technology research and development efforts to create room for industry growth. huge.

Industry analysts said that isophthaloyl chloride, as an important chemical raw material and pharmaceutical intermediate, At present, its industry shows good development prospects due to the continued favorable conditions upstream and downstream of the industrial chain. However, at present, there is a large gap between domestic isophthaloyl chloride products and leading foreign companies in terms of technology and quality. Affected by this factor, the domestic high-quality aramid fiber market has a low level of localization and still relies on imports. This situation is not only a challenge but also a huge opportunity for my country’s high-purity isophthaloyl chloride industry. In the future, as the high-end transformation trend of the meta-aramid industry continues to deepen, domestic demand for isophthaloyl chloride will continue to escalate, thereby driving the rapid development of the industry.
