Carbon Disulfide

Carbon disulfide is a colourless 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. [1] Pure carbon disulfide is a colourless liquid with a pleasant odour that is like the smell of chloroform. The impure carbon disulfide is contaminated with foul smelling impurities, such as carbonyl sulfide. Carbon disulfide evaporates at room temperature, and the vapour is more than twice as heavy as air. It easily explodes in air and also catches fire very easily. In nature, small amounts of carbon disulfide are found in gases released to the earth’s surface as, for example, in volcanic eruptions or over marshes. Commercial carbon disulfide is made by combining carbon and sulphur at very high temperatures. [2]
