The demand for 1,2-cyclohexanediamine is vast and my country’s supply capacity will continue to improve

1,2-Cyclohexanediamine, also known as 1,2-diaminocyclohexane, is an alicyclic diamine. It is a clear, colorless to light yellow transparent liquid at room temperature, with a slightly ammonia-like smell. 1,2-Cyclohexanediamine is sensitive to air, and long-term exposure to air can easily cause the product to turn yellow. 1,2-cyclohexanediamine exists in two isomers, cis and trans, and can be miscible with water in any proportion. However, the high water content of 1,2-cyclohexanediamine can easily affect the mechanical properties of the material.

According to the “China 1,2-cyclohexanediamine industry market in-depth research and development prospect forecast report from 2022 to 2027》shows that 1,2-cyclohexanediamine has a wide range of applications. As an epoxy resin curing agent, intermediate, etc., it is widely used in dyes, additives, medicines, pesticides, feed additives, wind power structural adhesives and other fields. 1,2-Cyclohexanediamine is a new type of amine curing agent with the advantages of low dosage and low cost. With the consumption upgrade, the application demand of 1,2-cyclohexanediamine will be further released.

The demand for 1,2-cyclohexanediamine is vast, but the industry lacks relevant production standards, resulting in uneven quality of 1,2-cyclohexanediamine products. In order to regulate market development and improve product quality, the “Industrial Use” was released in 2020 1,2-Cyclohexanediamine” group standard. my country’s 1,2-cyclohexanediamine production companies include Yueyang Changde New Materials, Shandong Platinum Pharmaceuticals, Sichuan Hengkang Technology, Hefei Tianjian Chemical, etc.

The preparation process of 1,2-cyclohexanediamine is mainly divided into two types, namely the epoxycyclohexane amination method and the high-pressure hydrogenation of adiponitrile to produce hexamethylenediamine by-product method. The epoxycyclohexane amination method uses epoxycyclohexane and liquid ammonia as raw materials to synthesize 1,2-cyclohexanediamine. In recent years, due to environmental protection and cost pressures, the production capacity of epoxycyclohexane has declined, resulting in The insufficient supply of 1,2-cyclohexanediamine has restricted the development of the 1,2-cyclohexanediamine market to a certain extent.

The process route of the by-product method of high-pressure hydrogenation of adiponitrile to hexamethylenediamine is complex, and for a long time, the preparation process of adiponitrile has been monopolized by overseas companies such as Invista and BASF. my country’s adiponitrile supply capacity is limited and market demand relies on imports. As a result, the price of 1,2-cyclohexanediamine remains high. In recent years, driven by policies, my country’s adiponitrile production technology has achieved breakthroughs. With projects under construction by companies such as Tianchen Qixiang, Huafeng Group, and Henan Shenma Group put into operation, it is expected that in the next three years, my country will have one million tons of adiponitrile. Adiponitrile production capacity is released. The increase in adiponitrile production capacity is good for the development of the 1,2-cyclohexanediamine industry. my country’s 1,2-cyclohexanediamine supply capacity is expected to increase in the future.

Industry analysts said that 1,2-cyclohexanediamine is a new amine curing agent that is used in wind power structural adhesives, dyes, Pesticides, pharmaceuticals, chemicals and other fields have broad development prospects. However, due to complex preparation processes, limited supply of raw materials, and lack of production standards, the market application of 1,2-cyclohexanediamine is subject to certain restrictions. 1,2-cyclohexanediamine is one of the by-products of adiponitrile. At present, my country has made breakthroughs in adiponitrile production technology. With the release of adiponitrile production capacity, the production scale of 1,2-cyclohexanediamine is expected to be further expanded.
