Adiponitrile is an Odorless, Light Yellow Liquid that is Relatively Soluble and has a Lower Density Than Water

Adiponitrile

The organic compound Adiponitrile has the chemical formula (CH2)4(CN)2. This colourless, viscous dinitrile liquid is a key precursor to the nylon 66 polymer. Around one million tonnes of adipic acid nitrile were manufactured in 2005. Many methods for synthesising adipic acid nitrile have been developed due to its industrial value. Furfural was used in the early commercial procedures, followed by the chlorination of butadiene to produce 1,4-dichloro-2-butene, which can be converted to 3-hexenedinitrile using sodium cyanide, and then hydrogenated to adipic acid nitrile.

The first stage of the process comprises monohydrocyanation (the addition of one molecule of HCN), which results in isomers of pentenenitriles as well as 2- and 3-methylbutanenitriles. The 3- and 4-pentenenitriles are isomerized from these unsaturated nitriles. In the last stage, these pentenenitriles are exposed to a second hydrocyanation to create adipic acid nitrile in an anti-Markovnikov sense. 3-pentenenitrile, which is generated after the first hydrocyanation, can undergo alkene metathesis to provide dicyanobutenes, which are easily hydrogenated as previously stated. 2-methylglutaronitrile is a valuable byproduct of adipic acid nitrile synthesis.

The main raw materials used in the production of Adiponitrile Market are butadiene and adipic acid nitrile. These materials come from refineries and are petroleum fractions. Butadiene hydrocyanation necessitates the use of natural gas for external heating. As a result, price fluctuations and the efficient use of natural gas have an impact on manufacturing costs and process efficiency. In the electrodimerization of acrylonitrile, however, the price of the raw material has a greater impact on manufacturing costs than other significant parameters. Adipic acid nitrile manufacturers' raw material selection is influenced by factors such as raw material availability and cost.

Lithium-ion batteries, enamels, paints, and varnishes all use Adiponitrile. It is used as an addition to the electrolyte in lithium-ion batteries at a very low concentration of up to 1% by weight of the electrolyte. The solution aids in the retention of battery power and improves overall performance. Adipic acid nitrile is used directly in the production of HMDA and as an addition in electrolyte solutions. Hexamethylene diisocyanate and nylon resin and fibre are both made with HMDA. The latter is employed as a polymerizing agent in the creation of polyurethane paints and coatings, as well as in the formulation of enamel coatings.
