As adiponitrile production capacity increases, the 2-methylpentanediamine market is expected to expand accordingly

2-Methylpentanediamine (MPMD) is a chemical raw material, an aliphatic amine, composed of a methyl branch chain and a five-membered carbon chain. As a new amine curing agent, chain extender, and curing treatment agent, 2-methylpentanediamine can be used in the production of spandex, fibers, coatings, sealing materials, pesticides, and composite materials. The product has the characteristics of transparency, fast curing, low melting point, and low crystallinity, and can replace the commonly used epoxy resin curing agent polyetheramine.

According to the “2022-2027 China 2-methylpentanediamine (MPMD) industry market in-depth research and development prospect forecast report released by the Industrial Research Center 》shows that in recent years, with the upgrading of demand and technological progress, domestic and foreign companies have become more enthusiastic about the development and modification of epoxy resin curing agents. As a new type of amine curing agent, in this context, 2- The methylpentanediamine market is also facing good development opportunities. Current suppliers of 2-methylpentanediamine include Invista, DuPont, Shell Chemical of the Netherlands, BASF of Germany, etc.

2-Methylpentanediamine is one of the main by-products of adiponitrile, also known as 1,4-dicyanobutane. With its excellent properties, adiponitrile is widely used in rubber, fiber, plastics, nylon and other fields. It is widely used. In my country, adiponitrile is mainly used to make nylon intermediates, accounting for about 90% of its consumption. For a long time, my country’s adiponitrile production capacity has been weak and its demand has basically relied on imports. Invista is the world’s largest adiponitrile producer.

The preparation methods of ethylenenitrile mainly include adipic acid ammoniation method, acrylonitrile electrolysis method, butadiene cyanide hydrogenation method, butadiene carbonylation method, etc. Among them, butadiene cyanide hydrogenation method is currently the most advanced adiponitrile method in the world. The production process is also the development direction of my country’s adiponitrile industry technology.

Butadiene cyanide hydrogenation method uses 3-pentenenitrile (3-PN) and hydrocyanic acid under the catalyst to generate adiponitrile and 2-methylglutaronitrile (MGN), and 2-methylglutaronitrile can be Hydrogenation further synthesizes 2-methylpentanediamine. 2-Methylpentanediamine is a by-product of ethylenediamine. A 1 million tons/year butadiene hydrocyanation adiponitrile unit can produce about 180,000 tons of 2-methylpentanediamine.

Adiponitrile is one of the key industrialization projects encouraged by the state. In recent years, thanks to technological progress, my country’s adiponitrile production capacity has been continuously improved. Relevant production companies include Tianchen Qixiang, Huafeng Group, and Henan Shenma Group. etc. It is expected that in the next three years, my country will have one million tons of adiponitrile production capacity released. With the expansion of ethanedinitrile production capacity, the scale of the 2-methylpentanediamine industry will also expand further.

Industry analysts said that with the upgrade of downstream demand, the market has put forward higher requirements for curing agent performance, technology, application, etc. As a new amine curing agent, 2-methylpentanediamine has attracted increasing market attention and is expected to be further developed and applied in the future. 2-Methylpentanediamine is an important by-product of ethylenediamine. Thanks to technological progress, my country’s ethylenediamine production capacity continues to increase, and the scale of the 2-methylpentanediamine industry will expand accordingly.
