The m-phenylenediamine (MPD) industry has huge room for development and local companies have competitive advantages in the global market.

Meta-phenylenediamine (MPD), also known as 1,3-phenylenediamine, has a chemical formula of C6H8N2 and is an organic compound. Meta-phenylenediamine appears as white needle-like crystals with an aromatic odor. It is soluble in water, acetone, ethanol, chloroform, and dimethylamide, and is insoluble in butanol, toluene and benzene. Meta-phenylenediamine has the characteristics of good moisture and gas barrier properties, good heat resistance, good corrosion resistance, and high reactivity. As an important organic synthetic raw material, it is widely used in synthetic resins, dyes, medicine and other fields.

The preparation methods of m-phenylenediamine include direct amination of aniline, iron powder reduction method and hydrogenation reduction method. The direct amination method of aniline refers to using aniline and ammonia as raw materials, using nickel and nickel-based oxides as catalysts, and reacting under high temperature and high pressure conditions to obtain finished products. This method has low yields; the iron powder reduction method refers to using Iron powder, hydrochloric acid, m-dinitrobenzene are used as raw materials, and the finished product is obtained through activation, reduction, filtration, washing, distillation and other processes; the hydrogenation reduction method requires hydrogenation, catalysis, pressurization, distillation and other processes to obtain the finished product. This method has the advantages of high yield, green and environmental protection.

Meta-phenylenediamine is widely used in synthetic resins, dyes, medicine and other fields. In the field of synthetic resins, m-phenylenediamine can be used as an epoxy resin curing agent; in the field of dyes, m-phenylenediamine can be used as a dye intermediate to produce direct sunfast black G, basic orange and other dyes; in the pharmaceutical field, Meta-phenylenediamine can be used to produce antibacterial drugs.

According to the “2023-2028 China m-phenylenediamine (MPD) industry market in-depth research and development prospect forecast report》shows that with the growth of market demand, the development space of m-phenylenediamine industry continues to expand. The global m-phenylenediamine market size will reach US$650 million in 2022, a year-on-year growth of 7.2%. In the future, as technology maturity improves and the development of downstream industries accelerates, the m-phenylenediamine market size will maintain a growth trend and will exceed US$1.2 billion by 2028.

The m-phenylenediamine industry has high technical barriers, and there are only a few companies in my country with large-scale production capabilities. Jiangsu Tianjiayi Chemical Co., Ltd., Zhejiang Longsheng Holding Group Co., Ltd., Anhui Liuguo Chemical Co., Ltd., Sichuan Northern Hongguang Special Chemical Co., Ltd., and Zhejiang Wanfeng Chemical Co., Ltd. are the main manufacturers of m-phenylenediamine in my country. . Zhejiang Longsheng is the largest m-phenylenediamine manufacturer in my country and even the world, accounting for nearly 70% of the global market. According to the annual report of Zhejiang Longsheng Enterprise, the company achieved revenue of 21.23 billion yuan in 2022, a year-on-year increase of 27.4%.

Industry analysts said that m-phenylenediamine has excellent performance and is widely used in many fields. In the future, with the gradual release of market demand, my country’s The prosperity of the phenylenediamine industry will further improve. In terms of market competition, Zhejiang Longsheng, as my country’s leading m-phenylenediamine enterprise, has competitive advantages in product quality in the global market. In the future, as local companies continue to exert their efforts, my country’s m-phenylenediamine market space will be further expanded.
