Repeated exposure causes skin sensitization and may cause central nervous system and liver damage. Routes of exposure include inhalation, oral, and to a certain extent dermal uptake (tested with volunteer humans and in rat studies). Pathways of exposure for humans include emissions, auto exhaust, and cigarette smoke that can expose the human subject directly if they inhale or smoke. It evaporates quickly at room temperature (20 ☌) to reach dangerous concentrations skin irritation, respiratory irritation, and eye irritation are the immediate effects of this exposure. Acrylonitrile increases cancer in high dose tests in male and female rats and mice and induces apoptosis in human umbilical cord mesenchymal stem cells. The mechanism of action of acrylonitrile appears to involve oxidative stress and oxidative DNA damage. Acrylonitrile is one of seven toxicants in cigarette smoke that are most associated with respiratory tract carcinogenesis. It is classified as a Class 2B carcinogen (possibly carcinogenic) by the International Agency for Research on Cancer (IARC), and workers exposed to high levels of airborne acrylonitrile are diagnosed more frequently with lung cancer than the rest of the population. The burning material releases fumes of hydrogen cyanide and oxides of nitrogen. Īcrylonitrile and derivatives, such as 2-chloroacrylonitrile, are dienophiles in Diels–Alder reactions.Īcrylonitrile is highly flammable and toxic at low doses. Typical protic nucleophiles are alcohols, thiols, and especially amines. 2 CH 3 − CH = CH 2 + 2 NH 3 + 3 O 2 ⟶ 2 CH 2 = CH − C ≡ N + 6 H 2 O In fact, the 2008–2009 acetonitrile shortage was caused by a decrease in demand for acrylonitrile. Acetonitrile and hydrogen cyanide are significant byproducts that are recovered for sale. In 2002, world production capacity was estimated at 5 million tonnes per year, rising to about 6 million tonnes by 2017. Production Īcrylonitrile is produced by catalytic ammoxidation of propylene, also known as the SOHIO process. Computer simulations suggest that on Titan conditions exist such that the compound could form structures similar to cell membranes and vesicles on Earth, called azotosomes. Īcrylonitrile has been detected in the atmosphere of Titan, a moon of Saturn. Īcrylonitrile is harmful to aquatic life. It decomposes by reacting with oxygen and hydroxyl radical to form formyl cyanide and formaldehyde. It has been detected at the sub-ppm level at industrial sites. Acrylonitrile is not naturally formed on Earth.
