| Fire hazards | Ignition temperature is dangerously low. Vapors may be ignited by contact with an ordinary (incandescent) light bulb. When heated to decomposition, it emits highly toxic fumes of oxides of sulfur. When heated to decomposition, emits highly toxic fumes of sulfur oxides and can react vigorously with oxidizing materials. Avoid air, rust, halogens, metal azides, metals, oxidantswhen exposed to heat or flame reacts violently with aluminum, chlorine, azides, hypochlorite, ethylamine diamine, ethylene imine, fluorine, metallic azides of lithium, potassium, cesium, rubidium and sodium, nitrogen oxides, potassium, zinc and (sulfuric acid plus permanganate). Decomposes on standing for a long time. (EPA, 1998)· HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames.Highly flammable. Many reactions may cause fire or explosion. Gives off irritating or toxic fumes (or gases) in a fire. Vapour/air mixtures are explosive. |
| Fire potential | Carbon disulfide vapor is explosive, igniting spontaneously on contact with sparks or at temperatures above 147 degrees C.The vapor ignites on contact with fluorine.Dangerous when exposed to heat, flame, sparks, friction, or oxidizing materials.The substance may ignite spontaneously on contact with hot surfaces ... Reacts violently with oxidants causing fire and explosion hazard. |
| Health hazards | The material affects the central nervous system, cardiovascular system, eyes, kidneys, liver, and skin. It may be absorbed through the skin as a vapor or liquid, inhaled or ingested. The probable oral lethal dose for a human is between 0.5 and 5 g/kg or between 1 ounce and 1 pint (or 1 pound) for a 70 kg (150 lb.) person. In chronic exposures, the central nervous system is damaged and results in the disturbance of vision and sensory changes as the most common early symptoms. Lowest lethal dose for humans has been reported at 14 mg/kg or 0.98 grams for a 70 kg person. Alcoholics and those suffering from neuropsychic trouble are at special risk. (EPA, 1998)· TOXICmay be fatal if inhaled, ingested or absorbed through skin. |
| Hazards summary | 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 temperaturesExposure to carbon disulfide occurs mainly in the workplace. Acute (short-term) inhalation exposure of humans to carbon disulfide has caused changes in breathing and chest pains. Nausea, vomiting, dizziness, fatigue, headache, mood changes, lethargy, blurred vision, delirium, and convulsions have also been reported in humans acutely exposed by inhalation. Neurologic effects, including behavioral and neurophysiological changes, have been observed in chronic (long-term) human and animal inhalation studies. Reproductive effects, such as decreased sperm count and menstrual disturbances, have been observed in humans exposed to carbon disulfide by inhalation. Animal studies support these findings. EPA has not classified carbon disulfide for human carcinogenicity.Liquid causes first degree burns on short exposure[CHRIS] Carbon disulfide has good warning propertiesits vapor is heavier than air. Elevation of liver function tests has been reported after acute exposure. [LaDou, p. 497-8] It can cause both acute and chronic encephalopathy. Alice Hamilton described in the 1920s two cases, one of slowly developing paralysis of the legs, the other of rapidly developing manic-depressive insanity. [Hamilton A. Exploring the Dangerous Trades. Beverly, MA: OEM Press, 1995, p. 389] There is limited evidence that CS2 can increase spontaneous abortion in humans and birth defects in animals. There is also evidence that CS2 can decrease sperm counts in experimental animals and reduce libido in exposed workers. [Frazier, p. 171-2] The risk of death from coronary heart disease was increased 2.5 to 5 fold in a studies of viscose rayon workers. [NIOSH Guidelines for Chemical Hazards] Viscous rayon workers suffered retinal hemorrhages and microvascular aneurysms. Optic nerve damage was also seen after heavy acute or chronic exposure. [Sullivan, p. 1209] Vigliani studied over 380 cases in Italy that occurred in the decades prior to 1953. He concluded that chronic exposure to at least 45 ppm was necessary to cause intoxication. [ACGIH] Heavy, chronic exposure to CS2 is associated with kidney disease as a secondary effect from the accelerated atherosclerosis. [LaDou, p. 423] See No evidence of cardiovascular toxicity in workers exposed below 5 ppm carbon disulfide. [PMID 26940896] |

| Disposal methods | Generators of waste (equal to or greater than 100 kg/mo) containing this contaminant, EPA hazardous waste number P022, D003, and F005, must conform with USEPA regulations in storage, transportation, treatment and disposal of waste.SRP: Wastewater from contaminant suppression, cleaning of protective clothing/equipment, or contaminated sites should be contained and evaluated for subject chemical or decomposition product concentrations. Concentrations shall be lower than applicable environmental discharge or disposal criteria. Alternatively, pretreatment and/or discharge to a permitted wastewater treatment facility is acceptable only after review by the governing authority and assurance that "pass through" violations will not occur. Due consideration shall be given to remediation worker exposure (inhalation, dermal and ingestion) as well as fate during treatment, transfer and disposal. If it is not practicable to manage the chemical in this fashion, it must be evaluated in accordance with EPA 40 CFR Part 261, specifically Subpart B, in order to determine the appropriate local, state and federal requirements for disposal.Carbon disulfide is a waste chemical stream constituent which may be subjected to ultimate disposal by controlled incineration. A sulfur dioxide scrubber is necessary when combusting significant quantities of carbon disulfide.A good candidate for liquid injection incineration at a temperature range of 650 to 1,600 °C and a residence time of 0.1 to 2 seconds. A good candidate for rotary kiln incineration at a temperature range of 820 to 1,600 °C and residence times of seconds for liquids and gases, and hours for solids. A good candidate for fluidized bed incineration at a temperature range of 450 to 980 °C and residence times of seconds for liquids and gases, and longer for solids.For more Disposal Methods (Complete) data for Carbon disulfide (8 total), please visit the HSDB record page. |
| Toxicological information | CDC-ATSDR Toxicological Profile |
| Body burden | All 8 samples of mother's milk from 4 urban areas of the U.S. contained carbon disulfide(1). Carbon disulfide was qualitatively detected in samples of mother's milk from Bayonne, NJ, Jersey City, NJ, Pittsburgh, PA, and Baton Rouge, LA(2). Diurnal 2-thiothiazolidine-4-carboxylic acid, an indicator of exposure to carbon disulfide, excretion in urine samples collected from viscose production workers ranged from 3.4 to 41.5 mmol(3). Urinary concentration of 2-thiothiazolidine-4-carboxylic acid (TTCA) of workers during the production of viscose rayon fibers ranged from not detected to 2.3 mg TTCA/g creatinine(4). Mean TTCA concentrations in urine of workers in the viscose industry were, mg/L (department): 1.96 (spool spinning), 5.06 (spinning of technical rayon), 6.55 (washing), 2.27 (post-treatment), and 1.14 (second aging)(5). |
| Treatment | Following oral exposure, administer charcoal as a slurry (240 mL water/30 g charcoal). Consider gastric lavage after ingestion of a potentially life-threatening amount of poison if it can be performed soon after ingestion (generally within 1 hour). Intravenous urea (0.5 to 1.5 g/kg) has been recommended to inactivate free carbon disulfide in the blood. The efficacy of this treatment is unknown. Following inhalation exposure, move patient to fresh air. Monitor for respiratory distress. If cough or difficulty breathing develops, evaluate for respiratory tract irritation, bronchitis, or pneumonitis. Administer oxygen and assist ventilation as required. Treat bronchospasm with inhaled beta2 agonist and oral or parenteral corticosteroids. If the exposure occurred through eye exposure, irrigate exposed eyes with copious amounts of room temperature water for at least 15 minutes. If the exposure occurred through dermal contact, remove contaminated clothing and wash exposed area thoroughly with soap and water. (T36) |
| Interactions | ... CS2 treatment significantly increased the contractile response /uterine contractions of mid-gestation rats/ to KCl, carbachol, and A23187. The increase to A23187 was the greatest. In vitro exposure to CS2 immediately suppressed carbachol-induced contraction but did not affect spontaneous and KCl-induced contractions.... signs of carbon disulfide poisoning in animals are intensified by reserpine, iproniazid, and amphetamine...It is now recognized that the neural responses to carbon disulfide are greatly influenced by the mineral content of the diet, at least in animals. A highly mineralized diet offering substantial protection from neurologic effects.Inclusion of equimolar mixt of carbon disulfide in oral dose of approx 4 LD50's of carbon tetrachloride (5 mmol/kg) to phenobarbitone-pretreated rats reduced the amt of liver injury due to carbon tetrachloride & prevented deaths.For more Interactions (Complete) data for Carbon disulfide (35 total), please visit the HSDB record page. |

| Environmental fate | TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 48(SRC), determined from a log Kow of 1.94(2) and a regression-derived equation(3), indicates that carbon disulfide is expected to have very high mobility in soil(SRC). Volatilization of carbon disulfide from moist soil surfaces is expected to occur(SRC) given a Henry's Law constant of 1.44X10-2 atm-cu m/mole at 24 °C(4). Carbon disulfide is expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 359 mm Hg(5). Utilizing the Japanese MITI test, 2% of the Theoretical BOD was reached in 4 weeks(6) indicating that biodegradation is not an important environmental fate process in soil(SRC).AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 48(SRC), determined from a log Kow of 1.94(2) and a regression-derived equation(3), indicates that carbon disulfide is not expected to adsorb to suspended solids and sediment in the water column(SRC). Carbon disulfide is expected to volatilize rapidly from water surfaces(3) based on a Henry's Law constant of 1.44X10-2 atm-cu m/mole at 24 °C(4). Estimated volatilization half-lives for a model river and model lake are 2.6 hours and 3.5 days, respectively(SRC). According to a classification scheme(5), BCFs of <6.1 and <60 in carp at 50 and 5 ug/L, respectively(6) suggest that bioconcentration in aquatic organisms is low to moderate(SRC). Utilizing the Japanese MITI test, 2% of the Theoretical BOD was reached in 4 weeks(6) indicating that biodegradation is not an important environmental fate process in water(SRC). Hydrolysis is not expected to be an important environmental fate process based on a half-life of over 1 year under alkaline conditions(7).ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), carbon disulfide, which has a vapor pressure of 359 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase carbon disulfide is degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals(SRC)the half-life for this reaction in air is estimated to be 5.5 days(SRC), calculated from its rate constant of 2.9X10-12 cu cm/molecule-sec(3). Carbon disulfide has a weak UV adsorption band at 317 nm(4) and, therefore, may be susceptible to direct photolysis by sunlight(SRC). However, photolysis is not considered to be a relevant loss mechanism for the chemical(SRC). |
| Food survey values | Seven samples of lima beans, five of common beans, two of lentils and one sample of mung beans, soybeans, and split peas that were analyzed contained a mean carbon disulfide concentration of 2.3 ppbrange was 1.8 to 3.1 ppb(1). Some of these samples were obtained from health stores and one was from a home garden where it was grown without the use of herbicides or insecticides(1). Stored grain has been fumigated with carbon disulfide in the past. The carbon disulfide concentration in 9 samples of wheat, range from 64 to 7,500 ppb although none was found in samples of corn, oats, corn meal, and corn grits(2). While one sample of bleached flour contained 23 ppb, other samples tested, including corn muffin mix, cake mixes, dried lima beans, noodles and rice, were free of the fumigant(2). With the exception of granola, which contained 11 ppb of carbon disulfide, none of the 18 samples of table-ready food items tested contained carbon disulfide(3). The items tested contained representative samples of most classes of food(3). In addition, samples of butter and margarine, cheese, peanut butter, and highly processed foods from the US FDA's market basket survey contained no carbon disulfide(3). However some ready-to-eat food products, specifically two samples of corn chips, and oat ring cereal contained 80, 230, and 95 ppb of carbon disulfide, respectively(3). In an FDA Survey of 549 food items for fumigant residues, 7 were found to contain carbon disulfide(4). The average concentration of carbon disulfide residues was 738 ppb(4). Carbon disulfide has been identified as a volatile component in chicken and beef flavor(5).Carbon disulfide was detected in the following fruits and vegetables sampled from a major wholesale market in Sydney, Australia between 1993 and 1995(1).

Applications & Uses
Description
For many years, carbon disulfide was manufactured by the reaction of charcoal with sulfur vapor at temperatures of 750– 1000 C, 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.
Uses
Carbon disulfide is used in the manufacture of regenerated cellulose rayon, cellophane, soil disinfectants, and electronicvacuum tubes. Other major uses are in theproduction of carbon tetrachloride, xanthates,thiocyanates, plywood adhesives, and rubberaccessories. It is also used as a solvent and asan eluant for organics adsorbed on charcoalin air analysis.
Uses
In the manufacture of rayon, carbon tetrachloride, xanthogenates, soil disinfectants, electronic vacuum tubes. Solvent for phosphorus, sulfur, selenium, bromine, iodine, fats, resins, rubbers.
Uses
Carbon disulfide is used as a raw material in the production of such things as rayon, cellophane, semiconductors, and carbon tetrachloride, and to make some pesticides. It is used as an industrial solvent and chemical intermediate to dissolve rubber to produce tires (ATSDR, 1996), as well as in grain fumigation, analytical chemistry research, degreasing, dry cleaning, and oil extraction (Finkel et al., 1983). Natural sources of carbon disulfide include the open ocean, coastal areas of high biological activity, microbial reduction of sulfates in soil, marshlands, and some higher plants where the source of carbon disulfide is the tree roots (Carroll, 1985; Khalil and Rasmussen, 1984). Previously, carbon disulfide was used as a pesticide, where it was typically mixed with carbon tetrachloride in a 20/80 mixture, respectively. This mixture was used to exterminate insects and rodents from entire boxcars of wheat, corn, rye, and other grains (Peters et al., 1988). Grain fumigators can be acutely intoxicated and may be chronically exposed to carbon disulfide. Therefore, in the late 1980s, all pesticides containing carbon disulfide as an active ingredient were cancelled by the United States Environmental Protection Agency (U.S. EPA) (U.S. EPA, 1999).
General Description
Pure carbon disulphide is a colourless liquid with a pleasant odour similar to that of chloroform, while the impure carbon disulphide is a yellowish liquid with an unpleasant odour, like that of rotting radishes. Exposure to carbon disulphide occurs in industrial workplaces. Industries associated with coal gasification plants release more of carbon disulphide, carbonyl sulphide, and hydrogen sulphide. Carbon disulphide is used in large quantities as an industrial chemical for the production of viscose rayon fibres. In fact, the major source of environmental pollution both indoor and outdoor by carbon disulphide is caused by emission released into the air from viscose plants.
Preparation & Synthesis
Preparation
Carbon disulfide is manufactured by heating sulfur vapor with charcoal, and condensing vapors of the compound formed. Alternatively, it may be obtained by heating sulfur with natural gas or petroleum fractions. Instead of sulfur, H2S may be used. The reaction occurs at very high temperatures. The product obtained in these reactions may contain sulfur impurities. Carbon disulfide is purified by distillation.
