Propionitrile Chemical Properties,Usage,Production

Chemical Properties Clear liquid Usage Propionitrile is an intermediate for organic syntheses, e.g. Houben-Hoesch reaction, as well as for pharmaceuticals, e.g. ketoprofen and fragrances. Product Data Sheet General Description A colorless liquid with an ether-like odor. Density 0.683 g / cm3. Flash point 61°F. Toxic by inhalation, skin absorption, and ingestion. Vapors are heavier than air. Used as a solvent, and to make other chemicals. Air & Water Reactions Highly flammable. Soluble in water. Reactivity Profile Propionitrile is incompatible with strong acids, strong bases, strong oxidizing agents and strong reducing agents. After refluxing for 24 hours at 221°F, a mixture of Propionitrile with N-bromosuccinimide exploded. Health Hazard Propionitrile is highly toxic. This super toxic compound has a probable oral lethal dose in humans of less than 5 mg/kg or a taste (less than 7 drops) for a 70 kg (150 lb.) person. It is a mild to moderate skin and eye irritant. Fire Hazard When heated to decomposition, Propionitrile emits toxic fumes of nitrogen oxides and cyanide. Propionitrile is a flammable/combustible material and may be ignited by heat, sparks or flames. Vapors may travel to a source of ignition and flash back. Container may explode in heat of fire. Vapor explosion and poison hazard indoors, outdoors or in sewers. Runoff to sewer may create fire or explosion hazard. Generates cyanide ions. Poisonous on contact with acids. stable, but may become unstable at elevated temperatures and pressures.
