CHEMICAL AND PHYSICAL PROPERTIES
| Physical Description | Carbon disulfide appears as a clear colorless to light yellow volatile liquid with a strong disagreeable odor. Flammable over a wide vapor/air concentration range (1%-50%). Vapors are readily ignited; the heat of a common light bulb may suffice. Insoluble in water and more dense than water. Hence sinks in water. Vapors are heavier than air. Used in the manufacture of rayon and cellophane, in the manufacture of flotation agents and as a solvent. |

PRODUCT INTRODUCTION
description
Pure carbon disulfide is a colorless liquid with a pleasant odor that is like the smell of chloroform. The impure carbon disulfide that is usually used in most industrial processes is a yellowish liquid with an unpleasant odor, like that of rotting radishes. Carbon disulfide evaporates at room temperature, and the vapor 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 sulfur at very high temperatures
