BUTYRONITRILE Chemical Properties,Usage,Production

Chemical Properties colourless liquid General Description A clear colorless liquid. Flash point 76°F. Less dense than water. Vapors heavier than air. Produces toxic oxides of nitrogen during combustion. Used in the manufacture of other chemicals. Air & Water Reactions Highly flammable. Slightly soluble in water. Reactivity Profile BUTYRONITRILE can react vigorously with oxidizing reagents, when heated to decomposition, BUTYRONITRILE emits highly toxic fumes of cyanides and oxides of nitrogen [Sax, 9th ed., 1996, p. 609]. Nitriles may polymerize in the presence of metals and some metal compounds. They are incompatible with acids; mixing nitriles with strong oxidizing acids can lead to extremely violent reactions. Nitriles are generally incompatible with other oxidizing agents such as peroxides and epoxides. The combination of bases and nitriles can produce hydrogen cyanide. Nitriles are hydrolyzed in both aqueous acid and base to give carboxylic acids (or salts of carboxylic acids). These reactions generate heat. Peroxides convert nitriles to amides. Nitriles can react vigorously with reducing agents. Acetonitrile and propionitrile are soluble in water, but nitriles higher than propionitrile have low aqueous solubility. They are also insoluble in aqueous acids. Health Hazard Dizziness, rapid respirations, headache, drowsiness, drop in blood pressure and pulse, delayed symptoms. May cause cyanosis (blue-grey coloring of skin and lips due to lack of oxygen) Fire Hazard Special Hazards of Combustion Products: Toxic cyanide fumes
