Acetonitrile Chemical Properties,Usage,Production

Chemical Properties Colorless liquid General Description A colorless limpid liquid with an aromatic odor. Flash point 42°F. Density 0.783 c / cm3. Toxic by skin absorption. Less dense than water. Vapors are denser than air. Air & Water Reactions Highly flammable. Water soluble. Reactivity Profile Acetonitrile decomposes when heated to produce deadly toxic hydrogen cyanide gas and oxides of nitrogen. Strongly reactive [Hawley]. May react vigorously with strong oxidizing reagents, sulfuric acid, chlorosulfonic acid, sulfur trioxide, perchlorates, nitrating reagents, and nitric acid. [Sax, 9th ed., 1996, p. 20]. Potentially explosive in contact with nitrogen-fluorine compounds (e.g., tetrafluorourea) [Fraser, G. W. et al., Chem. Comm., 1966, p. 532]. Health Hazard Exposure to 160 ppm for 4 hours causes flushing of the face and a feeling of constriction in the chest; 500 ppm for brief periods is irritating to the nose and throat. Severe exposures cause irritability, skin eruptions, confusion, delirium, convulsions, paralysis, and death due to central nervous system depression.
