Many domestic companies are actively deploying the hexamethylenediamine market and the future development of the industry is promising.


Hexamethylenediamine is an organic compound with the molecular formula C6H16N2. It appears as white powder and has a strong ammonia smell. It is easily soluble in water, ethanol and ether. Hexamethylenediamine can be produced in various ways, including adiponitrile method, adipic acid method, caprolactam method, hexanediol method, butadiene method, etc. However, the current large-scale and industrial production method of hexamethylenediamine is All are adiponitrile method.
The adiponitrile method is the mainstream production method for preparing hexamethylenediamine. The production path of this method can be divided into two categories: high pressure and low pressure. The high-pressure method refers to a method in which adiponitrile reacts with hydrogen to generate hexamethylenediamine under the action of a reaction temperature of 100-180°C, a reaction pressure of 30-35Mpa, and an iron-based catalyst; the low-pressure method refers to a method in which the reaction temperature is 60 A method for producing hexamethylenediamine through the addition reaction of adiponitrile and hydrogen at -100°C, reaction pressure of 1.8-3.0Mpa and the action of a nickel-based catalyst. Among them, the low-pressure method can prepare higher-purity hexamethylenediamine products, which has now become the dominant process route for the production of hexamethylenediamine.
Adiponitrile is the main raw material for the production of hexamethylenediamine. Due to the high technical barriers to its production, my country’s import dependence on adiponitrile is high. However, in recent years, with the increasing number of local adiponitrile companies and the continuous commissioning of related projects under construction and proposed, domestic adiponitrile production capacity has further increased. It is expected that in 2023, my country’s adiponitrile production capacity will be close to one million tons. The growing supply of raw materials in the upstream continues to benefit the development of the domestic hexamethylenediamine industry, and the industry has broad prospects for future development.
Nylon 66 is the main application field of hexamethylenediamine. Nylon 66 is a type of engineering plastic with excellent performance. Currently, it has been widely used in automobiles, electronics, medical, machinery, electric power, chemical industry, tires and other fields, and the market demand is relatively broad. As a key raw material for nylon 66, hexamethylenediamine is currently experiencing an increasing market demand as the production of nylon 66 continues to increase. Domestic nylon 66 production has reached 452,000 tons in 2022. Therefore, according to the“In-depth Market Research and Investment in the Hexamethylene Diamine Industry from 2023 to 2028” released by the Industrial Research Center “Strategy Recommendation Report” shows that the domestic hexamethylenediamine market size will reach 2.59 billion yuan in 2022.
At this stage, against the background of the increasing domestic demand for nylon 66 and the continuous maturation of hexamethylenediamine production technology, hexamethylenediamine is under construction and projects are increasing. For example, in July 2022, Shenma Group will produce 150,000 tons/year of high-quality hexamethylenediamine. The project has entered the substantial construction stage; in August 2022, Rongsheng Petrochemical announced a plan to invest 64.1 billion in the construction of high-end new material projects, including a 280,000 tons/year hexamethylenediamine device.
In addition, in 2022, there will be many companies such as Jiuyuan High-tech Materials, China Chemical, Hualu Hengsheng, Ruitai Technology, Xinhecheng Refining, Gulei Petrochemical, Huashen New Materials and other companies laying out the hexamethylenediamine track. Industry analysts people said that in the future, as domestic companies continue to exert their efforts, my country’s hexamethylenediamine production capacity is expected to continue increase, thereby continuously meeting the needs of the downstream application market and alleviating the problem of tight market supply, and the future development of the industry is promising.
