11/13/2023 0 Comments Carbon disulfide formula![]() ![]() Significant safety data come from the viscose rayon Industry, where both carbon disulfide as well as small amounts of H 2S may be present. The chemical formula for carbon disulfide is CS 2, and its molecular weight is 76.14 g/mol. Learn about the chemical structure, formula, and other names of carbon disulfide, a gas phase chemical compound. In 2007 Alfa Aesar stopped selling carbon disulfide samples.Īt very high levels, carbon disulfide may be life-threatening because it affects the nervous system. Dilution with nitrogen rendered contents inflammable. Johnson Mathey's sister company Alfa Aesar was the first company to introduce carbon disulfide in the form of pressurized bottle containing a solution of pressurized nitrogen, coupling agent, stablizer, and carbon disulfide, with an active carbon disulfide content of 85%. In this video well write the correct formula for Carbon disulfide (CS2). Worldwide exports of this chemical are negligible. Regulatory process names 5 Translated names 22 IUPAC names 11. Commercial AvailabilityĬS 2, being highly flammable and having one of the lowest autoignition temperatures, cannot be transported easily using commercial means. This conversion proceeds via the intermediacy of thiophosgene, CSCl 2.ĬS 2 is a ligand for many metal complexes, forming pi complexes. Sodium reduces CS 2 to give the heterocycle "dmit 2-": 3 CS 2 + 4 Na → Na 2C 3S 5 + Na 2Sĭirect electrochemical reduction affords the tetrathiooxalate anion: 2 CS 2 + 2e - → C 2S 4 2- ChlorinationĬhlorination of CS 2 is the principal route to carbon tetrachloride: CS 2 + 3 Cl 2 → CCl 4 + S 2Cl 2 Both xanthates and the related thioxanthates (derived from treatment of CS 2 with sodium thiolates) are used as flotation agents in mineral processing. This reaction is the basis of the manufacture of regenerated cellulose, the main ingredient of viscose rayon and cellophane. Nucleophiles such as amines afford dithiocarbamates: It is widely used in the synthesis of organosulfur compounds such as Metham sodium, a soil fumigant. These differences in reactivity can be attributed to the weaker π donor-ability of the sulfido centers, which renders the carbon more electrophilic. Carbon disulfide evaporates at room temperature, and the vapor is more than twice as heavy as air. 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. Although it is structurally similar to carbon dioxide, CS 2 is highly flammable:Ĭompared to CO 2, CS 2 is more reactive toward nucleophiles and more easily reduced. Pure carbon disulfide is a colorless liquid with a pleasant odor that is like the smell of chloroform. The reaction is analogous to the combustion of methane. Carbon Disulfide CS - structure, chemical names, physical and chemical properties, classification, patents, literature, biological activities. A lower temperature reaction, requiring only 600 ☌ utilizes natural gas as the carbon source in the presence of kieselgel or alumina catalysts: CH 4 + 1/2 S 8 → CS 2 + 2 H 2S C(S)S carbon disulfide,carbon disulphide,carbon bisulfide,dithiocarbonic anhydride,carbon bisulphide,schwefelkohlenstoff,weeviltox,wegla dwusiarczek,solfuro. CS 2 once was manufactured by combining carbon (or coke) and sulfur at high temperatures. Small amounts of carbon disulfide are released by volcanic eruptions and marshes. The formula for carbon disulfide is- CS2 C S 2. 3.1 Pressurized Liquid Nitrogen Based Sample.and Sills, R.C.: Covalent modification of hemoglobin by carbon disulfide: III.
