Nitrile-function compounds; acrylonitrile

HS code 292610 covers nitrile-function compounds, with a focus on acrylonitrile. This class of organic chemicals plays a crucial role in the production of a wide range of industrial and consumer products, from plastics and synthetic fibers to rubber and pharmaceuticals. As a key building block for many important materials, the nitrile-function compounds industry is a vital component of the broader chemical manufacturing sector and contributes significantly to global economic activity.

The primary production method for nitrile-function compounds, including acrylonitrile, is catalytic ammoxidation. This process involves the reaction of propylene, ammonia, and air over a metal oxide catalyst to form acrylonitrile. The reaction is carried out at elevated temperatures and pressures, with careful control of the reaction conditions to optimize yield and product quality. Downstream processing, such as distillation and purification, is then used to refine the acrylonitrile and other nitrile-function compounds for various applications.

The main inputs required for the production of nitrile-function compounds like acrylonitrile include propylene (a petrochemical feedstock), ammonia, and various catalysts. Propylene is typically derived from the refining of crude oil or natural gas processing, while ammonia is produced through the Haber-Bosch process. The catalysts used in the ammoxidation reaction are often based on metal oxides, such as those containing molybdenum, vanadium, or antimony. Additionally, utilities like steam, electricity, and cooling water are necessary for the manufacturing process.

The primary output of HS code 292610 is acrylonitrile, which is a versatile chemical used in the production of a wide range of products. Acrylonitrile is a key monomer for the manufacture of 390130 (acrylonitrile-butadiene-styrene (ABS) resins), 390190 other polymers of styrene, and 390310 (acrylonitrile-butadiene-styrene (ABS) copolymers), all of which are widely used in the plastics, automotive, and construction industries. Nitrile-function compounds produced under this code may also be consumed by industries producing 400240 (chloroprene (chlorobutadiene) rubber), 290529 other acyclic alcohols, and various pharmaceutical and agrochemical products.
