Pentylenediamine (DAMP) is a raw material for polyamide. my country’s industry is highly concentrated.

Pentamethylenediamine (DAMP) generally refers to 1,5-pentanediamine, with the molecular formula C5H14N2, and is an organic compound. Pentylenediamine appears as a colorless fuming liquid at room temperature, with a pungent odor similar to ammonia. It is soluble in ethanol and water, and slightly soluble in ether. Pentylenediamine has the advantages of good biocompatibility, good electrical properties, and good mechanical properties. It is widely used in organic synthesis, medicine, textiles, pesticides, engineering plastics and other fields.

The main preparation methods of pentamethylenediamine include biological transformation and chemical synthesis. Bioconversion methods can be subdivided into microbial conversion methods, direct extraction methods of organisms, direct microbial production methods, etc. The direct microbial production method refers to the use of fermentation processes to produce pentamethylenediamine using lysine, glucose, etc. as raw materials. This method has the advantages of good finished product quality and high production efficiency, but it has higher requirements for equipment and parameters. The chemical synthesis method refers to using glutaronitrile as raw material and converting it into pentanediamine under the action of a catalyst. This method has the advantages of low production cost and high technological maturity, but it can easily cause environmental pollution.

In recent years, the country has attached great importance to the development of the pentamethylenediamine industry and introduced many policies to support it. In January 2023, six departments including the Ministry of Industry and Information Technology jointly issued the “Three-Year Action Plan to Accelerate the Innovative Development of Non-Grain Bio-based Materials”. The document clearly proposed to further expand the application scope of bio-based chemicals and polymer varieties such as pentanediamine. Against this background, the prosperity of my country’s pentamethylenediamine industry will further improve.

According to the “2023-2028 China Pentamethylenediamine (DAMP) Industry Market In-depth Research and Development Prospects Forecast Report released by the Industrial Research Center 》 shows that pentamethylenediamine is mainly used in organic synthesis, medicine, textiles, pesticides, engineering plastics and other fields, among which the organic synthesis field is its largest demand end. Pentylenediamine can be used to make polyamide, diisocyanate, epoxy resin and urea-formaldehyde resin. Polyamide, commonly known as nylon, has the advantages of high tensile strength, good elasticity, and good wear resistance. It is widely used in fiber products, automobile manufacturing, industrial manufacturing and other fields. As the demand for polyamide applications grows, my country’s pentamethylenediamine market space will continue to expand.

my country’s pentamethylenediamine industry is highly concentrated, with two major manufacturers including Cathay Biotech and Xinghu Technology. Cathay Biotechnology focuses on the R&D, production and sales of polyamide and its derivatives. It has three production bases in Jinxiang, Wusu and Taiyuan. Currently, the company is actively promoting the annual production of 500,000 tons of pentanediamine and 900,000 tons of polyamide. Project construction.

           Industry analysts said that as an important base material for polyamide, the market demand for pentamethylenediamine continues to grow, and the industry prosperity has further improved. Benefiting from national policy support and the improvement of independent research and development capabilities of local enterprises, the development speed of my country’s pentamethylenediamine industry has accelerated. It is expected that in the future, as local companies continue to exert their efforts, my country’s pentanediamine production capacity will expand and output will further increase.
