개요

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 temperatures

Carbon disulfide (carbon bisulfide; CS2; CASRN 75-15-0), in its pure form is a colorless liquid that evaporates readily at room temperature, with a sweet aromatic odor similar to that of chloroform. In its impure commercial and reagent form, however, carbon disulfide is a yellowish liquid with a foulsmelling odor. It can be detected by odor at about 1 ppm but the sense of smell fatigues rapidly and, therefore, odor does not serve as a good warning property. It has a vapor pressure of 297mmHg and solubility in water by weight of 0.3% at 20 °C (68 °F). Once carbon disulfide is in the air it will break down into simpler substances within a few days after release (OEHHA, 2001).

Mechanism of Action · 1건

...The capacity of CS2 to cause a distal axonopathy ... is identical pathologically to that caused by hexane ... /CS2 reacts/ with protein amino groups to form dithiocarbamate adducts. The dithiocarbamate adducts of lysyl amino groups undergo decomposition to isothiocyanate adducts, electrophiles that then react with protein nucleophiles to yield covalent cross-linking. The reaction of the isothiocyanate adducts with cysteinyl sulfhydryls to form N,S-dialkyldithiocarbamate ester cross-links is reversible, while the reaction with protein amino functions form thiourea cross-links irreversibly. Over time, the thiourea cross-links predominate and are most likely the most biologically significant ... Analysis of cross-linking in erythrocyte proteins has verified that cross-linking occurs through thiourea bridges that accumulate with continuing exposure. Neurofilament cross-linking involves all 3 subunits and also demonstrates a cumulative dose response and temporal relationship consistent with a contributing event in the development of the axonal neurofilamentous swellings ... In addition to ... chronic axonopathy, CS2 can also lead to aberrations in mood and signs of diffuse encephalopathic disease. Some of these are transient at first and subsequently become more long-lasting, a feature that is common in vascular insufficiency in the nervous system. This fact, in combination with the knowledge that CS2 may accelerate the process of atherosclerosis, suggests that some of the effects of CS2 on the CNS are vascular in origin.

Biological Half-Life · 4건

Half-life for disappearance of /carbon disulfide/ from blood is estimated at less than 1 hour.

In vitro studies demonstrated that carbon disulfide readily combines with the amino acids in human blood, the half-life of this reaction being approximately 6.5 hours.

Metabolism/Metabolites · 6건

The metabolism for CS2-atheroma production also may involve direct injury to the endothelium coupled with hypothyroidism, because thiocarbamate (thiourea), a potent antithyroid substance, is a principal urinary metabolite of CS2.

A small amt of carbon disulfide is apparently converted to hydrogen sulfide, which is rapidly oxidized to sulfate and excreted in the urine.

Carbon disulfide reacts with a variety of nucleophilic functional groups ... amino, to form dithiocarbamic acids ... mercapto, to form trithiocarbamic acids ... hydroxyl, to form xanthogenic acids ... cmpd with two such groups to form heterocycles.

Carbon disulfide admin ip to rats was oxidized to (14)CO2 to an extent proportional to the amount of cytochrome P450 present in the liver at the time of admin.

Nitrogenase reduces carbon disulfide and can also be inhibited by this toxin. Carbon disulfide binds (in the form of AL CS2) mainly to hemoglobin and to a small extent to other blood proteins, such as albumin and gamma-globulin. Carbon disulfide is bioactivated by cytochrome P-450 to an unstable oxygen intermediate. The intermediate may either spontaneously degrade to atomic sulfur and carbonyl sulfide or hydrolyze to form atomic sulfur and monothiocarbonate. The atomic sulfur generated in these reactions may either covalently bind to macromolecules or be oxidized to products such as sulfate. The carbonyl sulfide formed may be converted to monothiocarbonate by carbonic anhydrase. Monothiocarbonate may further spontaneously degrade, regenerating carbonyl sulfide or forming carbon dioxide and sulfide bisulfide ion (HS-). The HS- formed can subsequently be oxidized to sulfate or other nonvolatile metabolites. Dithiocarbamates are the products of the reaction of carbon disulfide with amino acids. Most of the carbon disulfude absorbed is metabolized. Small traces of unchanged can be found in the urine. Carbon disulfide or carbonyl sulfide can conjugate with endogenous glutathione to yield thiazolidine-2-thione-4-carboxylic acid and 2-oxythiazolidine-4-carboxylic acid, respectively. Carbonic anhydrase 2 mediates the metabolism of carbon disulfide. (L592, A207, A208, A210, A211, A212)

개요For 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.

용도Carbon 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).

일반 설명Pure 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.

제조 방법 · 1건

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.
