Acrylonitriles are a group of chemical compounds characterized by the presence of a nitrile group attached to an alkene. The most common acrylonitrile is acrylonitrile, which is a colorless liquid with a distinctive odor. It is primarily used in the production of synthetic fibers, plastics, and resins, making it an important material in various industries. These compounds are produced through the process of propylene and ammonia reacting in the presence of oxygen. Acrylonitriles are known for their durability and resistance to chemicals, which makes them valuable in manufacturing products like acrylic fibers and ABS plastic. However, they can be toxic and require careful handling.
