8/7/2023 0 Comments Carbon disulfide cs2Note low flash point and very wide explosion limits. PEL: TWA 20 ppm, C 30 ppm ACGIH TLV: TWA 10 ppm. NIOSH REL: TWA 1 ppm, STEL 10 ppm, IDLH 500 ppm OSHA Individuals working in plants or laboratories using this substance should use adequate protective gear to avoid any exposure to this toxic chemical and prevent any health complication.Soluble in alcohol, ether, benzene, oil, chloroform and carbon tetrachloride.Ĭabbage-like odor detectable at 0.016 to 0.42 ppm (mean = 0.2 ppm)Ģ4.25 (atm?m 3/mol) at 24 ☌ (Elliott, 1989) Horses do not suffer from any side effects from use of this pesticide.Įxposure to Carbon Disulfide mainly occurs in the workplace. This is commonly used to control parasites in stables to protect horses from poisonous insects. The chemical formula for this substance is C5H10N2S2. Piperazine-Carbon Disulfide Complex is the name for Piperazine-1-Carbodithioic Acid. It is also seen to result in other acute discomforting symptoms like In humans, however, acute exposure by inhalation can lead to chest pain and respiratory changes. Some of the common organs areĪcute exposure to CS2 has resulted in less severe toxic effects in mice, rabbits and rats. Medical studies show temporary effects on specific organs of the animal body due to chronic exposure to this substance. This leads to the cancellation of the dipole moments arising due to each of the bonds. Simply put, there exists a 180° angle between the C-S bonds. Is Carbon Disulfide Polar?ĬS2 is a non-polar molecule because it has a linear geometric shape with a symmetric distribution of charge. The Lewis Structure is also simply represented as S = C = S. The “**” represent the valence electrons of S while the valence electrons of C are symbolized by “xx”. The “**” dots should be on top of each “xx” and the top and bottom of each S. The most appropriate Lewis Structure for CS2 can be drawn as Bond Order and Bond Length. In this structure, each dot stands for one electron. Carbon Disulfide Lewis StructureĪ Lewis symbol is a type of symbol that represents the electrons located in the valence shell of a simple ion or an atom as dots positioned around the letter that symbolizes the chemical element. It is also important to use a self-contained breathing equipment to avoid inhalation of this substance. In case of a large spill, these protective equipments should be worn along with full body suits and boots. Individuals using this material should wear lab coat, gloves, splash goggles and vapor respirators to prevent any physical damage arising out of exposure to CS2. The container should be tightly closed and kept in a well-ventilated spot that has a cool temperature. Like any other combustible substance, CS2 should be stored in a safe storage cabinet away from heat or any source of ignition. It can be absorbed with sand, dry earth or any other non-inflammable substance. Larger spills should be kept away from open flames, heat or any sort of ignition. Small spillage can be absorbed with an inert material and properly disposed of. In case of accidental spillage of this material, handling should be careful. Large fires from this material need the use of water spray, fog or alcoholic foam. Small fires from CS2 products can be controlled with dry chemical powders. The risk of explosion from this product due to mechanical impact is not known. CS2 products may be combustible in the presence of static discharge. It can be combustible in the existence of open flames and sparks of oxidizing substances. This is an inflammable substance that has an auto-ignition temperature of 90 ☌ or 194 ☏. The MSDS (Material Safety Data Sheet) for Carbon Disulfide is as follows: Flammability In thermodynamic temperature, its B.P is 319 K. The boiling point (B.P) of CS2 is 46.3 ☌ or 115 ☏. The log octanol or water partition coefficient of CS2 is between 1.84 and 2.16. The vapor pressure for this substance is 352.6 mm Hg at 25 ☌.However, commercial CS2 grades have a foul odor that is similar to that of rotten eggs. It has an odor threshold that is of 0.05 mg/m3. Pure CS2 emits a sweet odor similar to chloroform. This substance is inflammable and quickly evaporates at room temperature.In its pure form, CS2 appears as a colorless liquid that is almost insoluble in water.Know about some of the main physical properties of CS2. It is also used for fumigation in grain elevators, bins, airtight storage warehouses, shipholds, cereal mills, barges and airtight flat storages. It is also used as a disinfectant in the soil to ward off nematodes (roundworms) and insects. It is also used as a pesticide for nursery stock and also in the conservation of fresh fruits. It is also used in purifying single-walled nanotubes of carbon. This liquid is used as a solvent for substances like This substance is used in the manufacture of diverse products like CS2 is used for diverse purposes like Manufacturing
