Properties and handling. Acrylonitrile is a colorless, flammable liquid with a boiling point of 171°F. It is traded commercially as technical grade (99%) and is bulk shipped in lined tank cars or trucks with the hazardous material markings. The linings are necessary due to the corrosive nature of acrylonitrile. 

Benzene is a clear, colorless, flammable liquid with a pleasant characteristic odor, bp 80.1°C, flash point -11.1°C, and ignition temperature 538°C. Benzene has been found to be very toxic and is on the list of Known to Be Human Carcinogens published every two years by the Department of Health and Human Services under the National Toxicology Program (NTP). There are four top 50 chemicals on this worst carcinogen list benzene 1,3-butadiene ethylene oxide and vinyl chloride. There are also four chemicals in the top 50 on the Reasonably Anticipated to Be Human Carcinogens list acrylonitrile, ethylene dichloride, formaldehyde, and propylene oxide. 

Acrylonitrile is transported by rail car, barge, and pipeline. Department of Transportation (DOT) regulations require labeling aciylomtnle as a flammable liquid and poison. 

SAFETY PROFILE A human poison by inhalation. Experimental poison by inhalation, intraperitoneal, subcutaneous, and intravenous routes. Moderately toxic by ingestion and skin contact. Experimental reproductive effects. Corrosive. A severe skin and eye irritant. An allergen and sensitizer. Mutation data reported. Flammable liquid when exposed to heat, flame, or oxidizers. Can react violently with acetic acid, acetic anhydride, acrolein, acrylic acid, acrylonitrile, aUyl chloride, CS2, chlorosulfonic acid, epichlorohydrin, ethylene chlorohydrin, HCl, mesityl oxide, HNO3, oleum, AgC104, H2SO4, p-propiolactone, or vinyl acetate. To fight fire, use CO2, dry chemical, alcohol foam. When heated to decomposition it emits toxic fumes of NOx and NH3. See also AMINES. 

EXPLOSION and FIRE CONCERNS combustible NFPA rating Health 3, Flammability 2, Reactivity 0 flammable liquid when exposed to heat, flame or oxidizers reacts violently with acetic acid, acetic anhydride, acrylic acid, acrylonitrile, allyl chloride, carbon disulfide, chlorosulfonic acid, hydrochloric acid, nitric acid, sulfuric acid, ethylene chlorohydrin, oleum, acrolein, or vinyl acetate heating to decomposition emits carbon monoxide, carbon dioxide, hydrocarbons, toxic oxides of nitrogen, and toxic amine vapors use water spray, dry chemical, alcohol foam, or carbon dioxide for firefighting purposes.

PAN, which is also known as Orion in its fibre form, is made from the monomer acrylonitrile. Acrylonitrile, with the formula (CH2=CH-CN), is a toxic, acrid smelling, extremely flammable liquid. In contact with skin or the eyes it produces severe irritation. Inhalation or prolonged skin contact at high concentrations can produce confusion, unconsciousness, and even death. Acrylonitrile is also known as cyanoethylene or vinyl cyanide, and can be found in PAN as a remnant. There are suspicions that acrylonitrile can cause brain cancer [35, 36], and it is classified as a possible human carcinogen (lARC Group 2B). 

Flammability and Explosibility Highly flammable liquid (NFPA rating = 3). Vapor forms explosive mixtures with air at concentrations of 3 to 17% (by volume). Hazardous gases produced in fire include hydrogen cyanide, carbon monoxide, and oxides of nitrogen. Carbon dioxide or dry chemical extinguishers should be used to fight acrylonitrile fires. 

A. Acrylonitrile is a flammable liquid, and its vapors can easily form explosive mixtures in air. 

Unusual fire and explosion hazards Acrylonitrile is a flammable liquid. Its vapors can easily form explosive mixtures with air. All ignition sources must be controlled where acrylonitrile is handled, used, or stored in a manner that could create a potential fire or explosion hazard. Acrylonitrile vapors are heavier than air and may travel along the ground and be ignited by open flames or sparks at locations remote from the site at which acrylonitrile is being handled. 

For purposes of compliance with the requirements of 29 CFR 1910.106, acrylonitrile is classified as a class IB flammable liquid. For example, 7,500 ppm, approximately one-fourth of the lower flammable limit, would be considered to pose a potential fire and explosion hazard.

Acrylonitrile resembles VC, a carcinogen, in structure. It is a flammable, explosive liquid (b.p. 77 C, V.P. 80 mm at 20°C). AN is a component of acrylic and modacrylic fibers produced by copolymerization with other monomers, e.g., with methyl acrylate, Me-methacrylate, vinyl acetate, VC and VDC. Other major uses of AN include copolymerizations with butadiene and styrene to produce ABS polymers, and with styrene to yield SAN resins which are used in the manufacture of plastics. Nitrile elastomers and latexes are also made with AN, as are a number of other chemicals, e.g. acrylamide and adiponitrile. Acrylonitrile is also used as a fumigant. 

Acrylonitrile (ACRN) is a clear, colorless, volatile liquid with a slightly pungent odor. It is very toxic, highly flammable and unstable. It is classified as a carcinogen and a mutagen. The chemical formula for ACRN is ... 

Synonyms and trade names cyanoethylene, 2-propenenitrile, vinyl cyanide Use and exposure Acrylonitrile is a colorless, man-made liquid with a sharp, onion- or garlic-like odor. It can be dissolved in water and evaporates quickly. Acrylonitrile is used principally as a monomer in the manufacture of synthetic polymers, polyacrylonitriles, acrylic fibers, and other chemicals such as plastics and synthetic rubber. A mixture of acrylonitrile and carbon tetrachloride was used as a pesticide in the past. - Acrylonitrile is highly flammable and toxic. It undergoes explosive polymerization. The... 

Polymer electrolytes are used in lithium ion rechargeable batteries. Pure polymer electrolyte systems include polyethylene oxide (PEO), polymethylene-polyethylene oxide (MPEG), or polyphosphazenes. Chlorinated PVC blended with a terpoly-mer comprising vinylidene chloride/acrylonitrile/methyl methacrylate can make a good polymer electrolyte. Rechargeable lithium ion cells use solid polymer electrolytes. Plasticized polymer electrolytes are safer than liquid electrolytes because of a reduced amount of volatiles and flammables. The polymer membrane can condnct lithinm ions. The polymer membrane acts as both the separator and electrolyte [7],...
