Butanediamine is a key raw material for nylon 46. Only DSM in the world has industrial mass production capabilities.


Butanediamine, also known as 1,4-butanediamine, 1,4-diaminobutane, and putrescine, is an organic compound with the chemical formula C4H12N2. Butanediamine appears as colorless crystals or colorless to slightly yellow liquid at room temperature. It has the smell of hexahydropyridine, is easily soluble in water, is easy to burn and explode, and is highly corrosive.
Butanediamine mainly exists in archaea and eubacteria. It is a common type of biogenic amine, which mainly plays a role in promoting cell development in organisms. Butanediamine is an important raw material for the production of engineering plastics and can react with adipic acid to form Cotton nylon 46 can also be used to prepare nylon 6 and nylon 66; in addition, butanediamine is also the key to biochemical preparations, agricultural chemicals, acid gas absorbers, chemical intermediates, surfactants, biological precursors and other products Material. At present, butanediamine has a wide range of application fields, among which engineering plastic nylon 46 is its main application market.
Nylon 46, also known as polybutylene adipamide, refers to an aliphatic polyamide formed by the condensation polymerization of butanediamine and adipic acid. Nylon 46 has the advantages of high hardness, high rigidity, high strength, good wear resistance, strong impact resistance, good creep resistance, strong fatigue resistance, and good electrical insulation. It is currently mainly used in automobiles, electronics, electricity, Scenes with high requirements on heat resistance and fatigue strength in machinery and other fields belong to a category of materials with high technical content. Under the background of the continuous expansion and development of the application fields of nylon 46, the demand for butanediamine, as its key raw material, continues to increase, and the industry development trend is improving.
According to the “China Butanediamine Industry Market Monitoring and Future Development Prospects Research Report 2023-2027” released by the Industrial Research Center , The industrial production of butanediamine is a process in which hydrogen cyanide and acrylonitrile are used as raw materials, a succinonitrile intermediate is generated through a chemical reaction, and then the large-scale production of butanediamine is realized through the hydrogenation process. Due to technical limitations, currently only one company in the world, DSM, has the industrial production capacity of butanediamine. And due to limitations in raw materials, this company also occupies the major share of the global nylon 46 market. my country does not yet have the mass production capacity for butanediamine and nylon 46, and this product mainly depends on imports.
Industry analysts said that butanediamine is an important chemical raw material, which is mainly used in nylon 46 Manufacturing field. As a type of nylon product with better comprehensive properties than nylon 6 and nylon 66, nylon 46 is expected to continue to expand its market size against the backdrop of rising automotive lightweight development trends, which will in turn drive increasing demand for butanediamine. However, the global butanediamine and nylon 46 market is still dominated by DSM. There are no companies with mass production capabilities in my country yet. In the future, local companies will need to increase technology research and development and accelerate product development.
