Carbon Disulfide - CS2

What is Carbon Disulfide?

CS2 is an organosulfur compound and a volatile liquid with chemical name Carbon Disulfide. It is also called Carbon bisulfide or disulfidocarbon or methanedithione.

Carbon Disulfide is a solvent for sulfur, bromine, fats, rubber, phosphorus, asphalt, selenium, iodine, and resins. It has been widely used to purify single-walled carbon nanotubes and in the manufacturing of flotation agents.

Carbon disulfide is flammable, colorless to light yellow, poisonous, volatile liquid which has a strong disagreeable smell. It has a flash point value of -22°F and is Insoluble in water. It is denser than water, therefore, sinks in it.

CS2 Uses (Carbon Disulfide)

  • Carbon Disulfide is used in the production of carbon tetrachloride.
  • Used as preparing soil disinfectants.
  • Used in the manufacturing of rayon.
  • Used as a solvent for iodine, phosphorous, etc.
  • Used to manufacture electronic vacuum tubes.
  • Used as a solvent in rubber making industries.
  • Used in camphor.
  • Used in generating petroleum catalysts.
  • Used as pesticide intermediate.

Carbon Disulfide Reactions

    • Reacts with oxygen produces carbon dioxide and sulfur dioxide.

CS2 + 3 O2 → CO2 + 2 SO2

    • Sodium sulfide undergoes a reaction to produce trithiocarbonate:

Na2S + CS2 → [Na+]2[CS32−]

    • Carbon disulfide is reduced with sodium to produce sodium 1,3-dithiole-2-thione-4,5-dithiolate and sodium trithiocarbonate.

4 Na + 4 CS2 → Na2C3S5 + Na2CS3

CS2 + 3 Cl2 → CCl4 + S2Cl2

Health Hazards

It affects the CNS, eyes, liver, skin, cardiovascular system, and kidneys. It is absorbed through the skin in its liquid or vapor form, ingested or inhaled. The likely oral lethal dose for humans is between 0.5 to 5 grams per kilogram person. Also, it leads to disturbance of vision and sensory changes. The lowest lethal dose for a human is reported as 14 mg/kg person.

Frequently Asked Questions

Is carbon disulfide an acid?

Carbon disulfide with formula CS2 is a colorless volatile liquid. The compound is commonly used in organic chemistry as a building block, as well as a non-polar industrial and chemical solvent. This has a “ether-like” odor but usually industrial samples are polluted with impurities that smell foul.

Where does carbon disulfide come from?

Limited quantities of carbon disulfide are present in nature in gasses emitted to the earth’s surface, e.g. in volcanic eruptions or over marshes. Microorganisms may also create carbon disulfide-containing gas in soil. Commercial carbon disulfide is produced at very high temperatures by adding carbon and sulphur.

Is carbon a metal?

Carbon is a non-metal material with solidity. Pure carbon can occur in all kinds of ways. The two most popular are diamond and graphite. Graphite is unique in that it is a non-metal transmitting electricity.

Is carbon disulfide made of atoms or molecules?

Since the molecules consist of atoms, it is not right to assume that carbon disulfide is made of atoms. Know, a molecule has special properties. And no atom has the carbon disulfide properties. Only molecules of carbon disulfide have the properties of carbon disulfide, and it is made of molecules.

What intermolecular forces does carbon disulfide have?

All the molecules of carbon dioxide and a carbon disulfide are non-polar. Carbon disulfide molecule (CS2): C-S bond is non-polar in CS2 since carbon and sulfur have identical electronegativies, the intermolecular attractions are London dispersion forces
