Modern plants achieve a 99.99% pure carbon disulfide product by means of fractional distillation. Vapours are readily ignited and the heat of a common light bulb may be sufficient.Ĭarbon disulfide is insoluble in water and denser than water.Ĭarbon disulfide is also useful for the manufacturing of rayon and cellophane.Ĭarbon disulfide, CS2, is a highly volatile, flammable, clear, colorless, dense liquid that has many useful chemical and physical properties.Īn industrially important chemical for over one hundred years, most carbon disulfide is now produced by reaction of hydrocarbon gas with sulfur in a process developed in the 1950s, although many small capacity plants still employ a retort or electric furnace route based on wood charcoal and sulfur. When coke reacts with Sulphur at high temperatures, Carbon disulfide produces carbon disulfide.Ĭarbon disulfide is linear in the shaping compound and used as an industrial and chemical non-polar solvent.Ĭarbon disulfide is also useful as a building block in organic chemistry.Ĭarbon disulfide displays aesthetic properties too.Ĭarbon disulfide has a strong disagreeable odor.Ĭarbon disulfide boiling point is 46 degrees C. Insoluble in water and more dense (10.5 lb / gal) than water.Ĭarbon disulfide is used in the manufacture of rayon and cellophane, in the manufacture of flotation agents and as a solvent.Ĭarbon disulfide is a highly toxic and flammable dangerous chemical compound.Ĭarbon disulfide releases during volcanic eruptions and marshes. Vapors are readily ignited the heat of a common light bulb may suffice. However, the general population living near viscose plants may also be exposed to carbon disulfide emissions.įor many years, carbon disulfide was manufactured by the reaction of charcoal with sulfur vapor at temperatures of 750– 1000C, but by the mid-twentieth century, especially in the United States, the process was superseded by the reaction of natural gas (principally methane) with sulfur.Ī clear colorless to light yellow volatile liquid with a strong disagreeable odor.įlammable over a wide vapor/air concentration range(1%-50%). ![]() The ventilation discharge from viscose plants can reach several millions of m3 per hour, with a carbon disulfide content varying from 20 to 240 mg/m3, which represents a total emission of 15-40 tonnes of carbon disulfide daily.Įxposure to carbon disulfide is mostly confined to those engaged in technological processes in the viscose industry. In this technological process, for every kilogram of viscose produced, about 20-30 g of carbon disulfide and 4-6 g of hydrogen sulfide are emitted.Īdditional release of carbon disulfide, carbonyl sulfide and hydrogen sulfide takes place from coal gasification plants data on the total emission from these plants are not available. The technical product is a yellowish liquid with a disagreeable odour.Ĭarbon disulfide is used in large quantities as an industrial chemical for the production of viscose rayon fibres. GHG carbon dioxide carbon disulfide global climate change.Carbon disulfide (CS2) in its pure form is a colourless, volatile and in-flammable liquid with a sweet aromatic odour. ![]() SO2 is an indirect contributor to CO2 formation and is implicated in global climate change. CS2 and COS additionally are implicated in the formation of SO2 in the stratosphere and/or troposphere. The five mechanisms of CO2 formation are as follows: Chemical Interaction of CS2 and hydrogen sulfide (H2S) present in natural gas at high temperatures, resulting in CO2 formation Combustion of CS2 in the presence of oxygen producing SO2 and CO2 Photolysis of CS2 leading to the formation of COS, CO, and SO2, which are indirect contributors to CO2 formation One-step hydrolysis of CS2, producing reactive intermediates and ultimately forming H2S and CO2 Two-step hydrolysis of CS2 forming the reactive COS intermediate that reacts with an additional water molecule, ultimately forming H2S and CO2. The purpose of this study is to identify five mechanisms by which CS2 and the breakdown products of CS2 contribute to atmospheric concentrations of CO2. The heat-trapping nature of CO2 has been found to increase the surface temperature, resulting in regional and global climate change. The breakdown products of CS2 carbonyl sulfide (COS), carbon monoxide (CO), and sulfur dioxide (SO2) are indirect greenhouse gases (GHGs) that contribute to CO2 levels in the atmosphere. CS2 and other associated sulfide compounds were found by this study to be present in emissions from unconventional shale gas extraction and processing (E&P) operations. This study identifies multiple mechanisms by which CS2 contributes to the formation of CO2 in the atmosphere. Carbon disulfide (CS2) has been historically associated with the production of rayon, cellophane, and carbon tetrachloride.
