what is acrylonitrile used for


It's classified as an organic compound simply because it's mostly composed of carbon and hydrogen atoms. It is used to make certain plastics, rubbers, and chemicals, and in the past, as a pesticide. With this low boiling point, acrylonitrile is sometimes referred to as a volatile compound, which means that the liquid acrylonitrile molecules readily escape into the gas phase and evaporate. If you work in an industry that uses acrylonitrile, please read chemical labels and the accompanying Safety Data Sheets for hazard information. [4] In terms of its molecular structure, it consists of a vinyl group linked to a nitrile. The reactants pass through the reactor only once, before being quenched in aqueous sulfuric acid. 26 0 obj <> endobj

[8], Acrylonitrile has been detected in the atmosphere of Titan, a moon of Saturn. ABS is notable for its use in the construction of Lego bricks, but it's also used for things like golf club heads, protective head gear, and automotive bumpers.

[5] In fact, the 2008–2009 acetonitrile shortage was caused by a decrease in demand for acrylonitrile. Acrylonitrile is a colorless, liquid, man-made chemical with a sharp, onion or garlic-like odor.

It is used to make certain plastics, rubbers, and chemicals, and in the past, as a pesticide.
[9][10][11] Computer simulations suggest that on Titan conditions exist such that the compound could form structures similar to cell membranes and vesicles on Earth. It may cause cancer. Create your account, Already registered? Routes of exposure include inhalation, oral, and to a certain extent dermal uptake (tested with volunteer humans and in rat studies). It turns out that acrylonitrile itself can be polymerized into a substance called 'polyacrylonitrile'.
Let's start by introducing acrylonitrile before we move on to other topics. Because acrylonitrile evaporates quickly, it is most likely to be found in the air around chemical plants where it is made. Almost all PAN resins are copolymers made from mixtures of monomers with acrylonitrile as the main monomer. Acrylonitrile and derivatives, such as 2-chloroacrylonitrile, are dienophiles in Diels–Alder reactions. [21], It evaporates quickly at room temperature (20 °C) to reach dangerous concentrations; skin irritation, respiratory irritation, and eye irritation are the immediate effects of this exposure. It is a colorless volatile liquid although commercial samples can be yellow due to impurities. Acrylonitrile (CH₂=CHCN) is a toxic, colorless to pale-yellow liquid, harmful to the eyes, skin, lungs, and nervous system. Create an account to start this course today.
