O-phenylenediamine (OPD) production capacity and output continue to grow, and my country’s industry concentration is high

                   O-Phenylenediamine (OPD), also known as 1,2-phenylenediamine and 1,2-diaminobenzene, has a chemical formula of C6H8N2 and is an organic compound. O-phenylenediamine appears as colorless monoclinic crystals, is soluble in ether, ethanol and chloroform, and is slightly soluble in water. O-phenylenediamine is often used as an intermediate material and is widely used in pesticides, medicines, dyes, rubber, chemical industry and other fields.

The preparation methods of o-phenylenediamine include o-nitroaniline hydrogenation reduction method, o-nitroaniline and sodium sulfide reduction method, and o-dichloroaniline ammonialysis method. The o-nitroaniline hydrogenation reduction method refers to using o-nitroaniline as raw material, passing in hydrogen in the presence of a catalyst, and obtaining the finished product through a reduction reaction. This method has problems such as poor quality of the finished product, and has not yet achieved industrial production; o-nitroaniline The reduction method of aniline and sodium sulfide is the mainstream preparation method of o-phenylenediamine. This method uses o-nitroaniline and sodium sulfide as raw materials and reacts under high temperature and high pressure to obtain the finished product.

o-Nitroaniline is the core raw material of o-phenylenediamine, accounting for nearly 70% of its production cost. At present, my country’s o-nitroaniline industry as a whole is in short supply, and its products are highly dependent on imports. Against this background, the market price of o-nitroaniline in my country continues to rise, driving the production cost of o-phenylenediamine to further increase. It is expected that in the future, with the improvement of technological maturity, the market price of o-nitroaniline in my country is expected to decrease, and the development speed of o-phenylenediamine industry will be accelerated by then.

         O-phenylenediamine is mainly used in pesticides, medicines, dyes, rubber, chemical industry and other fields. At present, the pesticide field is the largest demand end for o-phenylenediamine, accounting for nearly 60%. Pesticides and fungicides such as thiophanate-methyl, carbendazim, and mebendazole are o-phenylenediamine end products. In recent years, driven by market demand, my country’s o-phenylenediamine production capacity has expanded rapidly and output has continued to grow. According to the “2023-2028 China o-phenylenediamine (OPD) industry market in-depth research and development prospect forecast report》shows that my country’s o-phenylenediamine production capacity will reach nearly 80,000 tons in 2022, and its output will reach nearly 60,000 tons.

In terms of market competition, my country’s o-phenylenediamine industry is highly concentrated, with Guangxin Chemical, Shengda Chemical, Bayi Chemical, Lanfeng Biochemical, Yangnong Chemical, etc. being the main manufacturers in my country. Guangxin Co., Ltd. is my country’s leading o-phenylenediamine enterprise. It focuses on the research and development, production and sales of o-phenylenediamine, nitrochlorobenzene and other chemical products. It has o-phenylenediamine clean production technology. At present, the company’s o-phenylenediamine The annual production capacity reaches 25,000 tons.

          Industry analysts said that in recent years, the industry prosperity of o-phenylenediamine as a pesticide intermediate has been continuously increasing. In terms of market competition, my country’s o-phenylenediamine industry is highly concentrated, with leading companies occupying a dominant position in the market. It is expected that in the future, as local companies continue to optimize production processes, my country’s o-phenylenediamine industry will gradually develop in a green and high-quality direction.
