Carbon disulfide

Carbon disulfide is a colorless volatile liquid with the formula CS2. The compound is used frequently as a building block in organic chemistry as well as an industrial and chemical non-polar solvent. It has an "ether-like" odor, but commercial samples are typically contaminated with foul-smelling impurities.

Chemical Properties

Carbon disulfide is a linear molecule, with carbon at the center. CS2 is a symmetric molecule and therefore, is non-polar. This compound is less dense than water and the liquid is highly volatile. It is classified as a nitrile in organic chemistry, though it is a unique kind of nitrile due to its structure.

Production

Carbon disulfide is produced industrially by combining carbon and sulfur. This process involves heating sulfur and charcoal. The resulting chemical reaction can be represented as follows:

C + 2S → CS2

The reaction is exothermic, producing a combustion flame.

Uses

Carbon disulfide is used as a solvent in the manufacturing of cellophane and rayon, and in the preparation of carbon tetrachloride. It is also used in the production of rubber chemicals, floatation agents, and in the synthesis of organosulfur compounds.

Health Effects

Exposure to carbon disulfide can affect the nervous system and can cause psychological disorders. It is also harmful to the cardiovascular system and kidneys. It is classified as a hazardous substance and its use is regulated in many jurisdictions.
