O-Nitrochlorobenzene has a wide range of applications and greening is the main direction of industry development.

       O-Nitrochlorobenzene, also known as o-chloronitrobenzene and 2-chloronitrobenzene, has a chemical formula of C6H4ClNO2 and is an organic compound. O-Nitrochlorobenzene appears as a light yellow crystalline powder with an odor similar to nitrobenzene. It is soluble in organic solvents such as ether, acetone, benzene and ethanol, but insoluble in water. O-Nitrochlorobenzene is an important organic synthesis intermediate and is widely used in rubber accelerators, dye auxiliaries, pesticide industry, spice industry, pharmaceuticals and other fields.

The production of o-nitrochlorobenzene needs to be carried out under high temperature conditions. Catalysts are used to catalyze chlorobenzene, acetic anhydride, etc., and the finished product is obtained through nitric acid reaction. The main production methods of o-nitrochlorobenzene include three types: series annular nitrifier nitrification method, annular nitrator and kettle type mixed series nitrification method, and series kettle type nitrification method. In recent years, with the gradual implementation of national environmental protection policies, my country’s o-nitrochlorobenzene industry has begun to develop in the direction of energy conservation and environmental protection, and green synthesis processes have become a hot spot in industry research.

There are many derivatives of o-nitrochlorobenzene, including o-chloroaniline, o-nitrophenol, o-nitroaniline, o-aminobenzyl (ethyl) ether, etc. O-Chloroaniline can be used as an intermediate for synthetic resins, medicines, and pesticides, and the market demand is strong. my country’s o-chloroaniline production capacity is approximately 40,000 tons/year. Driven by downstream demand, the development speed of the o-nitrochlorobenzene industry will continue to accelerate. At present, the main players in my country’s o-chloroaniline market include Jining Jintai Lihua Chemical Technology Co., Ltd., Jiangsu Hengxiang Chemical Co., Ltd., etc.

o-Nitrochlorobenzene is mainly used in rubber accelerators, dye auxiliaries, pesticide industry, spice industry, pharmaceuticals and other fields. In the field of rubber accelerators, o-nitrochlorobenzene can be used to produce rubber accelerator DM, rubber accelerator M, etc.; in the field of dye auxiliaries, it can be used to produce orange-based GR, yellow-based GC, etc.; in the field of pesticide industry, it can be used to produce Carbendazim, thiophanate methyl, thiophanate, etc.

According to the “2023-2027 o-Nitrochlorobenzene Industry In-depth Market Research and Investment Strategy Suggestions Report released by the Industrial Research Center , the main players in my country’s o-nitrochlorobenzene market include Anhui Zhongxing Chemical Technology Co., Ltd., Anhui Bayi Chemical Co., Ltd., Jiangsu Yangnong Chemical Co., Ltd., Jiaxing Zhonghua Chemical Co., Ltd., Liaoning Shixing Pharmaceutical Co., Ltd., etc. . Bayi Chemical is my country’s largest o-nitrochlorobenzene manufacturer. The company’s o-nitrochlorobenzene production capacity reaches nearly 300,000 tons/year, ranking first in the industry.

Industry analysts said that there are many o-nitrochlorobenzene manufacturers in my country and the market competition is fierce. As an important organic synthesis intermediate, o-nitrochlorobenzene has many derivatives and its application fields are constantly expanding. As market demand is gradually released, the industry development trend will continue to improve. In recent years, Chinese companies have continued to increase improvements in the production process of o-nitrochlorobenzene, and greening will become the mainstream trend in industry development.
