  Définition

  Clear, colorless or faintly yellow, flammable liquid; almost odorless when pure; the commercial article has a strong disagreeable odor; poisonous! Specific gravity 1.260 at 25/25 °C; b.p. 46.2 °C; freezing point -111 °C... flash point -22 °F; ignition point under some conditions as low as 100 °C. Explosive limits in air 1-50% by volume. Soluble in alcohol, benzene, and ether; slightly soluble in water. Uses: In viscose rayon; cellophane... solvent for fats, resins, rubber, waxes, sulfur, and other chemical products... Danger: Extremely flammable. Vapor harmful.
  
  A yellowish, mobile, heavy liquid (CS₂), b.p. 46.3 °C (115 °F), having a distinctive and unpleasant odor. Its most noteworthy property is its sensitivity to heat; it has the lowest ignition point of any industrially used liquid, 100 °C (212 °F), and a flash point of -30 °C (-22 °F). Even frictional heat is sufficient to ignite it, and it is likely to explode if heating occurs when the liquid is partially confined, as in a beaker or flask. The fumes of carbon disulfide are poisonous, and the greatest care should be exercised in all aspects of handling and storage.

  Note :

  Manufactured by heating carbon, or such carbon-containing materials as charcoal, with sulfur in a furnace, its major uses are as a solvent for many organic materials (cellulose, rubber, synthetic resins, waxes, etc.), in the manufacture of regenerated cellulose products (cellophane and viscose rayon), and in the production of carbon tetrachloride. It also finds use as solvent extraction medium and as a fumigant. It is classed as an inorganic compound.
