      Mar 9, H.R. (th). To amend ti United States Code, to provide a presumption of service connection for certain specified diseases and disabilities in the case of veterans who were exposed during military service to carbon tetrachloride. In , a database of bills in the U.S. Congress. carbon tetrachloride a clear, colorless, mobile liquid used as a solvent. The most common route of poisoning is by inhalation of its vapors; it can also be absorbed through the skin. Toxicity results from depression of central nervous system activity and degeneration of the liver and kidneys. Signs of acute poisoning include nausea, vomiting, diarrhea.

    Carbon tetrachloride seemed an ideal choice. Easily and cheaply made, it performed well, but the discovery that it was also highly toxic meant that by the s it had been replaced by tetrachloroethylene (known in the trade as 'perc' for its older name perchloroethylene), which has continued in use to the present day, though this too is now being replaced because of .

Carbon tetrachloride (CCl 4), a volatile inorganic compound, is a very well-described 4 was once widely used as a dry cleaning solvent, precursor to refrigerant synthesis, propellant for aerosol cans, a fire extinguishing liquid, as a solvent for oils, fats, and lacquers, as a grain fumigant and curiously enough, in lava lamps [30, 31].

IUPAC Standard InChIKey: VZGDMQKNWNREIO-UHFFFAOYSA-N CAS Registry Number: Chemical structure: This structure is also available as a 2d Mol file or as a. website: © Mikhail Polyanskiy. database: public domain via CC0 NO GUARANTEE OF ACCURACY - Use on your own risk. Carbon tetrachloride, also known as carbon tet or Fr is a chemical compound.

Its chemical formula is CCl 4. It contains carbon in its +4 oxidation state and chloride ions. Properties. It is a colorless liquid. It smells like ether. It evaporates quite quickly.

It can EC Number: Carbon Tetrachloride book Value Units Method Reference Comment; Δ f H° gas ± kJ/mol: AVG: N/A: Average of 6 values; Individual data points Quantity Value Units Method Reference Comment; S° gas,1 bar J/mol*K. This test method covers the determination of the activation level of activated carbon.

Carbon tetrachloride (CCl 4) activity is defined herein as the ratio (in percent) of the Carbon Tetrachloride book of CCl 4 adsorbed by an activated carbon sample to the weight of the sample, when the carbon is saturated with CCl 4 under conditions listed in this test method.

Carbon tetrachloride (CCl 4) is a powerful hepatotoxin used extensively to generate liver necrosis and steatosis in rats, with the free radical generation as the possible mechanism of action. Although the OS involved in CCl 4 intoxication is unlikely to occur during physiopathological conditions, CCl 4 intoxication in rats provides.

Carbon tetrachloride, also called tetrachloromethane, a colourless, dense, highly toxic, volatile, nonflammable liquid possessing a characteristic odour and belonging to the family of organic halogen compounds, used principally in the manufacture of dichlorodifluoromethane (a refrigerant and propellant).

First prepared in by the reaction of chloroform with chlorine, carbon. CAS number: 56–23–5 NIOSH REL: 2 ppm ( mg/m 3) minute STEL; NIOSH considers carbon tetrachloride to be a potential occupational carcinogen as defined by the OSHA carcinogen policy [29 CFR ]. Current OSHA PEL: 10 ppm TWA, 25 ppm CEILING, ppm 5-min MAXIMUM PEAK in any 4 hours.

OSHA PEL: 2 ppm ( mg/m 3) TWA. Carbon tetrachloride is a clear, nonflammable liquid which is almost insoluble in water. (1) Carbon tetrachloride has a sweet characteristic odor, with an odor threshold above 10 ppm. (1) The vapor pressure for carbon tetrachloride is mm Hg at 20 C, and its log octanol/water partition coefficient (log K ow) is (1) Conversion Factors.

Carbon tetrachloride (CCl 4) is regarded as highly toxic. It is a known animal carcinogen and a potential human carcinogen. CCl 4 has become a model for the study of agents that cause localized cellular injury via a free-radical mechanism. This monograph is. Carbon tetrachloride is a manufactured chemical that does not occur naturally.

It is a clear liquid with a sweet smell that can be detected at low levels. It is also called carbon chloride, methane tetrachloride, perchloromethane, tetrachloroethane, or benziform.

Carbon tetrachloride is most often found in the air as a colorless gas. It is not flammable and does not. Also known as: Carbon tet, Perchloromethane, CCl4, Carbon chloride, Tetrachloromethane, Perc Chemical reference number (CAS): Carbon tetrachloride (Carbon tet) is a non-flammable colorless liquid with a heavy, sweet odor.

Beforecarbon tet was widely used as a cleaning fluid in home and industry. Untilthe chemical was used as a grain fumigant. Carbon tetrachloride was tested for carcinogenicity by various routes of administration. It produced liver neoplasms in mice and rats and mammary neoplasms in rats following subcutaneous injection.

In one study in mice by inhalation, an increased incidence of phaeochromocytomas was reported. In experiments involving administration of carbon.

Carbon tetrachloride is a solvent used primarily as a feedstock in the production of hydrochlorofluorocarbons, hydrofluorocarbons and hydrofluoroolefins and in the manufacturing of other chlorinated compounds and petrochemicals. The Montreal Protocol and Title VI of the Clean Air Act Amendments of called for a complete phase-out of carbon.

Carbon tetrachloride is a man-made volatile organic chemical that was used as a household spot remover, an industrial degreasing agent, in dry cleaning, in fire extinguishers, and as a grain fumigant to kill insects.

Most of these uses have been discontinued. Carbon tetrachloride was also used to make refrigerants and propellants for aerosol. A meta description is an HTML tag in the HTML code of your website, which allows you to customize a section of text that describes the page itself.

It plays a role in how your page is seen by search engine crawlers, and how it appears in SERPs. The ATSDR toxicological profile succinctly characterizes the toxicologic and adverse health effects information for the hazardous substance described here.

Each peer-reviewed profile identifies and reviews the key literature that describes a hazardous substance's toxicologic properties. Other pertinent literature is also presented, but is described in less. Carbon tetrachloride and mixtures containing it (with the exception of chemicals containing unavoidable residues of carbon tetrachloride that do not result in atmospheric concentrations of carbon tetrachloride greater than 10 ppm) are banned from consumer Size: KB.

Carbon Tetrachloride is even a favorite of avid stamp collectors. It has the ability to make water marks more visible and it also removes grease. Thus a stamp collector would be able to check the authenticity of a stamp while cleaning the paper.

Carbon Tet (its nickname in the lab) was even used as a way to dry clean clothes in the early 20th. Carbon tetrachloride definition: a colourless volatile nonflammable sparingly soluble liquid made from chlorine and carbon | Meaning, pronunciation, translations and examples. Carbon Tetrachloride Health Effects.

Carbon tetrachloride is readily absorbed by all routes of exposure (inhalation, oral and dermal) in both humans and experimental animals. Once absorbed it is widely found in fat but also in blood.

Carbon tetrachloride, an important industrial solvent, is prepared by the chlorination of methane at K. What is the equilibrium constant for the reaction at K? Would the reaction vessel need to be heated or cooled to keep the temperature of the reaction constant?
