CS 2 is used for the cold vulcanization of rubber which is an essential process to give rubber its strength, elasticity, and resistance. The operation removes sulfides that accumulate on equipment surfaces during the week. Carbon disulfide (CS2) is a colorless liquid with an ether-like odor. (1,2) Carbon disulfide is also used to produce rubber chemicals and pesticides. Other routes of exposure Exposure can cause dizziness, poor sleep, headache, anxiety, anorexia, weight loss, and vision changes. It is also a valued intermediate in chemical synthesis of carbon tetrachloride.It is widely used in the synthesis of organosulfur compounds such as metam sodium, xanthates, dithiocarbamates, which are used in extractive … Carbon disulfide is used in the manufacture of rayon and cellophane. It is an important raw material for preparing viscose rayon and cellophane film. The level of exposure depends upon the dose, duration, and work being done. Carbon disulfide (CS2), also termed as carbon bisulfide, is a colorless, highly volatile, toxic, and flammable liquid chemical compound. It is used in the manufacture of xanthates. Drinking-water normally does not contain carbon disulfide. Carbon disulfide is a colorless liquid. So we investigated past working exposure to CS2 characteristics from surviving ex-workers of a rayon manufacturing plant … It can harm the eyes, kidneys, blood, heart, liver, nerves, and skin. It is an important raw material for preparing viscose rayon and cellophane film. Refer to Table 3 for its other uses. Si … Carbon disulfide is a highly volatile, flammable liquid with low ignition temperature. disulfide. Carbon Disulfide Market: Region wise outlook. , - < >- _ 1 . Food Carbon disulfide can contaminate juice and wine distilled from grapes harvested in vineyards treated with carbon disulfide (2). Carbon disulfide is used to manufacture rayon. Carbon disulfide is a highly volatile, flammable liquid with low ignition temperature. Formula: CS2 | CAS: 75-15-0. It is also used in the manufacturing of carbon tetrachloride. . When pure, it is nearly odorless, but the commercial product smells vile. It can be synthesized by reacting hydrocarbon gas with sulfur. Braeckman L, Kotseva K, Duprez D, De Bacquer D, De Buyzere M, Van De Veire N, Vanhoorne M. Vascular changes in workers exposed to carbon disulfide. '. Synonyms: methanedithione, carbon bisulfide. carbon disulfide during these processes is smail compared with that in the viscose industry. How to detect Carbon disulfide. Carbon disulfide, \text{CS}_2, is a colorless, highly flammable liquid used in the manufacture of rayon and cellophane.A sample contains 0.0205 mol \text{CS}_2.Calculate the mass of carbon disulfide in the sample. Most of carbon disulfide produced worldwide goes into manufacturing viscose rayon and cellophane film. Bythe purity segment, the market is bifurcated into impure carbon disulfide and pure carbon disulfide. Effects of exposure to carbon disulfide (CS2) on electrocardiographic features of ischemic heart disease among viscose rayon factory workers. It was used as a grain fumigant. USES 4.1 Uses 4.1.1 Uses 4.1.2 Description The principal industrial uses of carbon disulfide are the manufacture of viscose rayon, cellophane film, carbon tetrachloride and xanthogenates and electronic vacuum tube (Greenwood & Earnshaw, 1984 & Merck Index 1989). Solution: Let us first find the molar mass of \text{CS}_2. A neuro-ophthalmological examination, including fluorescein angiography, has been made of 100 male viscose rayon workers occupationally exposed to carbon disulfide … Two incidents occurred in a viscose rayon manufacturing process about a month apart during the same step of a semi‐monthly cleaning operation in a carbon disulfide recovery box. Viscose rayon fibres are used in the production of rayon filament textile yarn, rayon tire yarn, rayon stable fibre and Cellophane . It is volatile and flammable, and is used as a solvent, an insecticide, a building-block in organic chemistry, and in the manufacture of viscose rayon, cellophane, and bamboo fiber.Carbon disulfide is released naturally into the atmosphere … Int Arch Occup Environ Health. The principal industrial uses of carbon disulfide, consuming 75% of the annual production, are the manufacture of viscose rayon and cellophane film.. Such concerns have led to the development of new types of rayon such as lyocell. In Korea, Carbon disulfide (CS2) toxicity was an important social problem from the late 1980s to the early 1990s but there have been few large-scale studies examining the prevalence of diseases after CS2 exposure discontinuance. Material Name/lden ti fier Muwfacturer's Name Street Ad&ess City State Postal No Chemical Name CARBON DISULFIDE CS2 Molecular Weight - 76.1 Supplier's Name Street City Sta Postal CENTURY RAYON Impure type of carbon disulfide is widely used in the industrial process. Teepak, Inc., which manufactures cellulose food casings by means of the viscose process, has a plant in Danville, Illinois, that emits approximately 400,000 cubic feet per minute (cfm) of water-saturated air containing approximately 100 parts per million (ppm) of carbon disulfide … C 2 S may undergo hydrolysis catalyzed by nanosized titania and zirconia to form CO 2 and H 2 S. Application This substitution is expected to hamper the market growth of carbon disulfide. Carbon disulfide (CS 2) is a chemical intermediate best known for its historical use in the production of rayon, cellophane, and carbon tetrachloride. MATERIAL SAFETY DATA SHEET SECTION 1 : MATERIAL IDENTIFICATION & USE : CARBON DISULFIDE - used in Rayon, Dyes & Pesticides. Carbon disulfide is necessary to remove the cellulose to allow it to be further transformed into rayon, but it also has a unique and undesirable effect on humans. CS 2 and other associated sulfide compounds were found by this study to be present in emissions from unconventional shale … Considering the application segment, the market is fragmented into rayon, rubber, cleaning carbon nanotubes, perfumes, cellophane, and others. Uses. Subsequent processing of the fibre releases carbon disulfide in substantial quantities. To evaluate the effects of the occupational exposure to rayon manufacturing chemicals (RMC, containing predominantly carbon disulfide (CS(2)) and minor sulfuric acid) in a rayon factory on the basal transepidermal water loss (TEWL), barrier integrity (BI), and sequential increasing TEWL profiles. CS 2 is a versatile compound that is primarily used in the production of rayon and cellophane. . Workers can be seriously harmed by the chemicals used to make most rayon. Carbon disulfide is used primarily in the production of viscose rayon. 1– 3 Industrial emissions of CS 2 to the atmosphere have declined as textile manufacturing has shifted from the US to Asia, and the use of CS 2 in carbon tetrachloride production has been phased out. Carbon disulfide is a selective solvent and used as a fumigant and insecticide. Premium clothing and rayon textile industries are projected to further augment the carbon disulfide market in Europe owing to high disposable income of consumers in the region. Disturbances in sexual function, such as decreased libido and potency, have been reported in several studies on male workers exposed to carbon disulfide. Rayon remains an important fibre, although production has declined in industrial countries because of environmental concerns connected with the release of carbon disulfide into the air and salt by-products into streams.
