Carbon disulfide, also called carbon bisulfide, is a colorless, poisonous, and highly flammable liquid. It has a pleasant odor when pure, but usually contains impurities which have the odor of rotten eggs. Industries use carbon disulfide in making cellophane, insecticides, rayon, and carbon tetrachloride, an important solvent. Carbon disulfide can dissolve sulfur, iodine, waxes, and India rubber.
Carbon disulfide is made by heating coke and sulfur in an electric furnace. It can also be produced by heating iron disulfide and carbon. It boils at 46.5 °C and melts at -111.6 °C.
