Carbon Disulfide Formula

Carbon disulfide is a highly toxic and flammable dangerous chemical compound. It releases during volcanic eruptions and marshes. When coke reacts with Sulphur at high temperatures, it produces carbon disulfide. This article will explain about Carbon disulfide formula with examples. Let us begin it!

Carbon Disulfide Formula

What is Carbon disulfide?

Carbon disulfide is linear in the shaping compound and used as an industrial and chemical non-polar solvent. It is also useful as a building block in organic chemistry. It displays aesthetic properties too.

Carbon disulfide has a strong disagreeable odor. Its boiling point is 46 degrees C. Vapours are readily ignited and the heat of a common light bulb may be sufficient. It is insoluble in water and denser than water. Hence sinks in water. Vapors are heavier than air. It is also useful for the manufacturing of rayon and cellophane.


Its boiling point is 46.24 degrees C and the melting point is −111.61 °C. The impure carbon disulfide is usually useful for most industrial processes is a yellowish liquid with an unpleasant odor. Carbon disulfide evaporates at room temperature, and the vapor is more than twice as heavy as air. It easily explodes in the air and also catches fire very easily.

Commercial carbon disulfide is made by combining carbon and sulphur at very high temperatures Carbon Disulphide is a solvent for sulfur, bromine, fats, rubber, phosphorus, asphalt, selenium, iodine, and resins. It has been widely in use 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.

The formula for Carbon Disulfide:

Its formula is : \(CS_2\)

We obtained it as:

\(C + 2S → CS_2\)


It is useful in the following:

  • The production of carbon tetrachloride.
  • Preparing soil disinfectants.
  • The manufacturing of rayon.
  • As a solvent for iodine, phosphorous, etc.
  • To manufacture electronic vacuum tubes.
  • As a solvent in rubber making industries.

Carbon Disulfide common reactions:

  1. Reacts with oxygen produces carbon dioxide and sulfur dioxide.

\(CS_2 + 3 O_2 \rightarrow CO_2 + 2 SO_2 (g)\)

  1. Sodium sulfide undergoes the reaction to produce the trithiocarbonate:

\(Na_2S + CS_2 \rightarrow Na_2 CS_3\)

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

\(Na + 4 CS_2 \rightarrow  Na2C3S5 + Na_2CS_3\)

  1. Carbon tetrachloride is produced by chlorination of \(CS_2\)

\(CS_2 + 3 Cl_2 \rightarrow  CCl_4 + S_2Cl_2\)

Health Hazards due to \(CS_2\):

It affects the CNS, eyes, liver, skin, cardiovascular system as well as kidneys. It is absorbed through the skin in its vapor form too. The likely oral lethal dose for humans is between 0.5 to 5 grams per kilogram weight.  Also, it may lead to disturbance of vision and sensory changes.

Solved Examples on Carbon Disulfide Formula

Q.1: Calculate molar mass of Carbon disulfide.

Solution: Its formula is: \(CS_2\)

Its molar mass will be:

= 12.0107 + 2 × 32.065

= 76.1407 gram per mole.
