The market for chlorobenzonitrile is vast and the investment prospects for high-end products are good

Chlorobenzonitrile does not only refer to a certain chemical, but refers to chlorobenzonitrile compounds obtained after the chlorination reaction of benzonitrile, phthalonitrile or benzene tricarbonitrile, specifically including p-chlorobenzonitrile, o-chlorobenzonitrile Benzonitrile, 2,4-dichlorobenzonitrile, 2,6-dichlorobenzonitrile, 3,4-dichlorobenzonitrile and other products, among which p-chlorobenzonitrile and o-chlorobenzonitrile are the main chlorobenzonitriles product. The appearance of chlorobenzonitrile is mostly liquid or white crystals, needle crystals, and colorless transparent liquid. When exposed to the outside world, it can volatilize toxic gases, is insoluble in water, and is soluble in solvents such as ether and ethanol. It is a very important intermediate that can be used in medicine, pesticides, dyes and other fields.

In the early days, the production of chlorobenzonitrile was mainly concentrated in a few countries and regions such as Germany and France. With the rapid development of fine chemicals and other industries, chlorobenzonitrile gradually emerged in the pharmaceutical, pesticide, dye and other industries. The demand for chlorobenzonitrile is increasing year by year, which has led Japan, India and others to start researching and producing chlorobenzonitrile and its derivatives.

In the 1970s, the Dutch company Philips Duphar discovered that 2,6-dichlorophenamide derivatives had insecticidal activity. Research institutions and multinational companies in developed countries competed to develop a considerable number of new pesticide varieties that were efficient and safe against natural enemies and the environment. Among them, the famous commercial products include Philips Duphar’s Diflubenzuron, Ishihara’s Chlorfluuron, Shell’s Teflubenzuron, and Dow’s Hex-aflururon. As well as triazole insecticides and pharmaceutical fungicide XRD-5631 from Japan Combination Company.

In the 1990s, the application fields of the chlorobenzonitrile industry expanded and the industry continued to develop rapidly. The major global manufacturers are Bayer and Hoechst of Germany, AMAR Dye Chemical Company of India, Rhône-Poulenc of France, Mitsubishi Chemical Company of Japan and Kawasaki Chemical Co., Ltd., etc.

The research and development of chlorobenzonitrile in my country began in the 1950s. In the early days, chlorinated hydrolysis was mainly used to produce chlorobenzonitrile. However, this process has many reaction steps, complex processes, high production costs, and low output rates, and cannot meet the requirements well. Domestic demand for chlorobenzonitrile. By the end of the 20th century, with the development of China’s medicine, pesticides, dyes and other fields, China’s demand for chlorobenzonitriles continued to expand. Based on the huge domestic demand for chlorobenzonitriles, domestic researchers developed an ammonia oxidation production process to shorten the reaction process. , reduce production costs and greatly improve product output rate. After 2010, with the technological advancement of my country’s chlorobenzonitrile industry, domestic chlorobenzonitrile production has reached a certain scale.

In recent years, my country’s pharmaceuticals, dyes, pesticides, and other fine chemicals have continued to develop, driving the chlorinated benzonitrile market to increase and stimulating the development of the chlorinated benzonitrile industry. Co., Ltd., Jiangsu Changhai Chemical Co., Ltd., Laohekou Huachen Chemical Co., Ltd., Jiangxi Shilong Industrial Co., Ltd. and other manufacturing enterprises. According to the “In-depth Market Research and Investment Strategy Suggestions Report on Chlorobenzonitrile Industry 2023-2028” released by the Industrial Research Center, In 2022, China’s chlorobenzonitrile industry production capacity will be 49,000 tons.

Industrial analysts believe that chlorobenzonitriles are widely used in medicine, dyes, pesticides and other fields. With the development of downstream markets, In particular, the field of pharmaceutical intermediates continues to develop, and the demand for chlorobenzonitriles will continue to expand. However, because the existing chlorobenzonitrile production technology is not yet mature, there are still problems such as high energy consumption, low yield, and environmental pollution. There is still a certain gap between the high-end chlorobenzonitrile production technology and leading foreign companies; at the same time, domestic companies There is still room for improvement in product development and innovation. In the future, chlorobenzonitrile companies need to increase investment in research and development of production processes, optimize production processes, increase the supply capacity of high-end chlorobenzonitriles, and meet downstream high-end demand.
